Spend what's actually yours.

Your bank shows you one number. Rent is in that number. So is power, and the\n car rego you forgot about. Stash splits your pay into pockets, so the balance you see is a\n balance you can trust.

Three things, and none of them require handing over your internet banking password.

◑

Pockets, not a lump sum

Rent, groceries, petrol, savings — each gets its own pocket. On payday, Stash shares your\n pay across all of them in a single tap, and the leftover is genuinely leftover.

↥

Drop in a bank statement

Export a PDF or CSV from your banking app. Stash reads it on your device and files each\n transaction against a pocket. It even reconciles against the totals your bank printed, and\n refuses to import if the maths doesn't agree.

↗

See where you're heading

Net worth, assets, debts, and a forecast that tells you if you're about to run out —\n before you run out, rather than after.

\n\n

Your money is nobody else's business.

Your budget is encrypted on your device with a key made from your password. The key never\n leaves your phone. The server stores scrambled text it cannot read — which means nobody who\n runs Stash can see your balances, your transactions or what you spend it on. Not the developer.\n Not anyone who steals the database.

We'd rather tell you the limit than oversell it: read\n exactly what we store, and what encryption can't protect you from.

\n\n

Free. All of it.

Everything above is the whole app. There is no upgrade to buy, and there may\n never be one.

Privacy Policy

Last updated ${UPDATED}

\n\n

The short version. Your budget is encrypted inside your own browser, with a key\n derived from your password. Stash's server only ever receives the scrambled result. The operator\n cannot read your transactions, balances, pockets or assets — not because of a policy, but because\n the server does not hold the key.

Stash does not sell your data, does not run ads, does not use tracking or analytics, and does not\n share your information with anyone except the small number of suppliers listed below that are needed\n to actually run the app.

There is one honest limit on all of this, and it is set out in full under\n “What encryption does not protect you from”. Please read it.

\n\n

1. Who is responsible

Stash is operated by ${OPERATOR}, an individual based in New Zealand. Under the Privacy Act 2020\nthat makes the operator an “agency”, and this policy explains how your personal information is\nhandled. You can reach us at ${CONTACT}.

\n\n

2. What Stash collects, and why

Only what the app needs to function. There is no analytics, no advertising, no profiling and no\nthird-party trackers on any page.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

What	Why	Can the operator read it?
Your username	To identify your account.	Yes. It does not have to be your real name, and we suggest it isn't.
Your password	To log you in and to unlock your data.	No — it is never sent to the server. Your browser stretches it into a separate\nlogin key, and only that key is sent. The server stores a salted PBKDF2 hash of that key, so even the\nkey itself is not recoverable from the database.
Your budget — transactions, pockets, balances, assets, bills, notes, history	It is the app.	No. Encrypted with AES-GCM in your browser before it is sent. The server stores\nciphertext and could not decrypt it if it wanted to.
A small “hints” record	So the daily reminder job can decide whether to notify you, without being able to read your budget.	Yes — this part is not encrypted, and you should know exactly what is in it. It\nholds: your notification on/off settings; a count of transactions waiting to be sorted; and up\nto three dates — when your next bill is due, when your forecast runs out of money, and when a\nfixed mortgage rate ends. It contains no amounts, no payees, no account numbers and no descriptions.\nTurn notifications off and it is not used.
Push notification subscription — only if you turn notifications on	To send the reminder to your device.	Yes: an anonymous device address issued by your browser vendor, plus its encryption keys. It\nidentifies a browser, not a person.
Your IP address	Rate limiting only — to stop someone brute-forcing logins.	Yes, briefly. It is stored against a counter that expires automatically (within an hour for\nsignups, 15 minutes for logins) and is then gone.
A session token	To keep you logged in.	Yes. Expires; deleted when you log out.
Your email address — optional, and blank is a perfectly good answer	One thing only: to warn you if there is a security problem with Stash. No\nnewsletters, no product updates, no marketing, ever. If you don't give one, the account works\nexactly the same — you simply can't be warned directly.	Yes. You can add, change or remove it at any time in Settings, and removing it means we hold\nnone.
A record of sign-ins to your account	So you can see whether anyone else has been in it. Every attempt, successful or failed, with the\ntime, the IP address it came from and the browser used. Stash shows this list to you\n— Settings → Recent sign-ins. That is what it is for.	Yes. Kept for 90 days, then deleted automatically. Deleted immediately if you delete your account.\nThis does mean Stash stores your IP address against your account for that period; it is the only way\na sign-in record can tell you anything useful, and we would rather you could catch an intruder than\nprotect you from a fact you already gave your internet provider.
Error reports	So a bug that breaks the app for you gets noticed. Users don't file bug reports, they just stop\nopening the app.	Yes: an error message, a stack trace, the app version and your browser type. Never your\nbudget, balances, transactions or any field value — a stack trace names functions and line\nnumbers, not the numbers in your account.
Feedback you send us	To read it and fix things.	Yes — whatever you choose to type, plus your username.
Waitlist details — only if you fill in the waitlist form	To gauge whether the paid version is worth building, and to tell you if it ships.	Yes: your email address, whether you'd pay, what price you'd pay, and any note. You can ask us to\ndelete this at any time.
Bank connection — not available to anyone at present	Would let Stash fetch transactions automatically via Akahu.	See section 6. This is the one part that would not be end-to-end encrypted, and it\nis switched off for all accounts today.

\n\n

Stash does not ask for your date of birth, your address, your phone number, your IRD number or your\nbank login. It never will. If a page claiming to be Stash asks you for your internet banking password,\nit is not us — close it.

\n\n

3. What Stash does not do

No advertising, and no selling or renting of personal information to anyone, ever.
No analytics or tracking scripts — no Google Analytics, no pixels, no fingerprinting.
No sharing of your financial data with any third party.
No emails to you other than ones you have asked for or that we are legally required to send.

\n\n

4. What encryption does not protect you from

This is the part most apps leave out, so here it is plainly.

Stash's encryption happens in JavaScript that the Stash server sends to your browser. That\nmeans the encryption protects you from the server reading stored data — a leaked database, a\nstolen backup, a curious operator — and it does so completely.

It does not protect you from a malicious or compromised version of the app itself. If\nsomeone took control of the server, they could serve altered code that captured your data before it was\nencrypted. This is true of every web app that claims end-to-end encryption, including the well-known\nones; it is a property of the web, not a flaw unique to Stash. The only real cures are running code you\ncompiled yourself, or independently verifying what is served. We would rather tell you this than let the\nword “encrypted” do work it hasn't earned.

Encryption also cannot protect data on a device someone else can unlock. Use a screen lock.

\n\n

5. Where your data lives, and who else touches it

Stash runs on Val Town, a hosting provider whose servers are in the United States.\nYour encrypted budget and the items in the table above are stored there. That is a cross-border\ndisclosure under Information Privacy Principle 12: your budget itself is encrypted before it ever\nleaves your device, so what is transferred is unreadable ciphertext.

The only other parties involved:

Your browser vendor's push service (Google, Apple or Mozilla, depending on your\ndevice) — only if you turn notifications on, and only to deliver the notification. The content of a\nStash notification never contains an amount or a payee, precisely because the server does not know them.
Akahu — only for bank connections, which are currently switched off for everyone.

Nobody else. No advertisers, no data brokers, no analytics vendors.

\n\n

6. Bank connections (Akahu)

The paid “Pro” tier would connect your bank through Akahu,\nNew Zealand's open banking provider. It is not available to any user today and will not be\nturned on for anyone until Stash is properly accredited.

Being straight with you about the design: a bank connection needs a token that the server can\nuse to fetch your transactions in the background. A server that can use a token is a server that can read\nit. So the bank connection is the one feature that cannot be end-to-end encrypted the way the rest of\nStash is. The tokens would be encrypted at rest with a server-held key — which protects against a database\nleak, but not against the operator. If and when this ships, that trade-off will be stated at the point you\nturn it on, not buried here.

\n\n

7. Backups

Stash backs up accounts nightly, keeps 14 days of them, and permanently keeps one “best known” copy as\ninsurance against corruption. Backups are copies of your encrypted data — they are as\nunreadable to us as the live copy. You can also take a backup yourself at any time from Settings. When you\ndelete your account, every backup of it is deleted with it.

\n\n

8. How long it is kept

Your account data is kept until you delete it. Sessions expire on their own. Rate-limit records expire\nwithin the hour. We do not keep data we no longer need.

\n\n

9. Deleting your account, and getting your data out

Both live in Settings, and both work without asking us for anything:

Export my data — downloads everything as a file. It is produced in your browser,\nbecause your browser is the only place your data can be read.
Delete my account — permanently removes your account, your budget, every backup of\nit, your hints, your notification settings, your email address, your sign-in history, any error reports\nfrom your account, and your waitlist entry. It asks for your password and your username first, because\nit cannot be undone. There is no grace period and no copy left behind.

\n\n

10. Your rights

Under the Privacy Act 2020 you can ask for access to the personal information we hold about you\n(Principle 6) and ask us to correct it (Principle 7). In practice the app gives you both directly, but you\nare welcome to ask us instead: ${CONTACT}. We will respond within 20\nworking days.

If you are not happy with how we have handled your information, you can complain to the\nOffice of the Privacy Commissioner — privacy.org.nz,\n0800 803 909.

\n\n

11. If something goes wrong

If there is a privacy breach that is likely to cause serious harm, we will notify the Office of the\nPrivacy Commissioner and the people affected as soon as practicable — we aim to notify the Commissioner\nwithin 72 hours of establishing that a breach is notifiable, in line with their guidance.

How we would reach you: by email, if you gave us one — that is the only thing an\nemail address is used for. If you did not, we will use a notice in the app, a push notification if you\nhave them switched on, and a prominent notice on this site. That is a weaker channel, and it is the\nhonest reason the email field exists at all.

\n\n

12. Children

Stash is not aimed at children under 13 and we don't knowingly hold their information. If you believe a\nchild has created an account, email us and we will remove it.

13. Changes to this policy

If this policy changes in a way that matters, the date at the top changes and the app tells you the next\ntime you open it. We will not quietly widen what we collect.

Terms of Use

Last updated ${UPDATED}

\n\n

The short version. Stash is free, it is made by one person, it is not a bank and it\n is not financial advice. Your data is encrypted with your password — if you lose both your\n password and your recovery code, your data is gone permanently and nobody, including us, can get it\n back. Please read section 4.

\n\n

1. Who you are agreeing with

Stash is provided by ${OPERATOR}, an individual in New Zealand (\"we\", \"us\"). By creating an account you\nagree to these terms. If you don't, don't use it — and if you've already signed up, delete your account in\nSettings.

\n\n

2. Stash is free, and comes as-is

Stash costs nothing and is provided \"as is\", without warranties of any kind. It is a personal project,\nnot a company with a support desk. We try hard to keep it working and to keep your data safe, but we can't\npromise it will always be available, always correct, or free of bugs. Nothing in these terms limits any\nrights you have under New Zealand law that cannot lawfully be excluded.

\n\n

3. It is not financial advice

Stash shows you your own numbers and does arithmetic on them. It does not give financial advice, and\nnothing in it is a recommendation to spend, save, borrow, invest or do anything else with your money. Its\nforecasts are projections from what you have entered — they are not predictions, and they will be wrong if\nyour inputs are wrong. Decisions about your money are yours. If you need advice, talk to someone licensed\nto give it.

Imported transactions and connected balances can be incomplete or out of date. Your bank's own\nrecords are the authoritative ones, not Stash's. Do not rely on Stash to tell you whether a\npayment will clear.

\n\n

4. Your password is the only key — losing it means losing your data

Read this one properly. Your budget is encrypted with a key derived from your password.\nWe do not have that key, and we cannot reset it. This is the whole point: it is why we cannot read your\ndata, and it is why we cannot rescue it either.

You are given a recovery code when you sign up. It is the only other way in. Write it\ndown and keep it somewhere that is not your phone.

If you lose your password and your recovery code, your data is permanently and irrecoverably\ngone. Not \"gone unless you email support\" — actually gone. We will not be able to help you, no\nmatter how much we would like to. There is no back door, by design.

Keeping your password and recovery code safe is your responsibility, as is anything done by someone you\nlet into your account.

\n\n

5. The paid tier does not exist yet

Stash is currently free, in full. A paid \"Pro\" tier — mainly automatic bank\nconnection — is something we would like to build, but it depends on accreditation and on enough\npeople wanting it. It may never be released.

Joining the waitlist costs nothing, commits you to nothing, and is not a pre-order or a purchase. If Pro\never ships, everything that is free today stays free — we will not take a feature away from you and sell it\nback.

\n\n

6. Using Stash sensibly

Don't try to break into other people's accounts, don't attack or overload the service, don't use it for\nanything illegal, and don't upload other people's financial information without their say-so. We may\nsuspend or remove an account that does these things.

\n\n

7. If Stash shuts down

This is a personal project and it may not run forever. If it is going to be shut down, we will give you\nreasonable notice in the app and leave the export tool working so you can take your data with you. We\nwon't sell your data as part of any wind-down — it is encrypted, so there would be nothing to sell.

\n\n

8. Liability

To the extent the law allows, we are not liable for any loss arising from your use of Stash — including\nfinancial loss from decisions you make using it, loss of data, or the service being unavailable. Stash is\nfree, and this limit is part of why we can offer it at all. Again, nothing here removes rights you have\nunder New Zealand law that cannot be excluded.

\n\n

9. Changes

We may update these terms. If a change is significant, the app will tell you. Carrying on using Stash\nafter that means you accept the new terms.

\n\n

10. Law

These terms are governed by New Zealand law, and the New Zealand courts have jurisdiction.

Parked, not actioned. Read before opening signups to anyone\noutside the circle of people who already trust Riley personally.\n\n---\n\n## 1. The thing Riley noticed\n\nThe operator (Riley) can read every user's financial data without their password.\n\n| What | Where | Who can read it |\n|---|---|---|\n| Budget data (pockets, txns, assets, worth) | blob `bud_`, **plaintext JSON** | anyone with the Val Town login |\n| Akahu tokens | sqlite `mb_bank`, AES-GCM **encrypted with `APP_KEY`** | anyone with the Val Town login (they own `APP_KEY`) |\n| Passwords | sqlite `mb_users`, PBKDF2-SHA256 120k iters + per-user salt | **nobody** — this bit is fine |\n\nEncrypting with a key you own is not protection *from you*. It only protects\nagainst a leaked database.\n\n## 2. The fix, if we ever want it: E2E encrypt the budget blob\n\nDesign (do NOT half-build this — losing the key means losing user data):\n\n1. On signup, generate a random 256-bit **data key** (DK).\n2. Derive `Kpw` from the user's password (PBKDF2/Argon2, **different salt+params\n from the auth hash** — never reuse the auth derivation).\n3. Derive `Krc` from their recovery code the same way.\n4. Store DK **twice**: `wrap(DK, Kpw)` and `wrap(DK, Krc)`. Server holds only\n ciphertext, never DK.\n5. Client encrypts state with DK before `POST /api/state`; decrypts after `GET`.\n6. Password change = re-wrap DK with the new `Kpw`. Recovery reset = unwrap with\n `Krc`, re-wrap with new `Kpw`. **Data survives both.**\n\n### Two honest costs\n\n- **Crons go blind.** `notify.ts` reads budget data to detect shortfall / bills\n due / inbox count. Encrypted, it can't. Those checks must move client-side\n (compute on app open, schedule a local notification) or we keep a tiny\n plaintext \"hints\" blob — which leaks a little, so decide deliberately.\n- **Bank tokens can NOT be E2E encrypted** while a server-side cron refreshes\n them. Something on the server must decrypt them to call Akahu. Either accept\n that narrower exposure, or drop background refresh and sync only when the app\n is open.\n\n## 3. Cheap fixes worth doing regardless\n\n- **No rate limiting** on `/api/login` or `/api/recover/*` → brute-forceable.\n- **Sessions never expire** (`mb_sessions` has `created` but nothing reads it).\n- **Password minimum is 6 chars**, no complexity rule.\n- Delete one-off admin/debug scripts after use (they're the read-anything hole).\n- Consider an audit log of any operator data access.\n\n---\n\n## 4. Akahu: the real wall to a public release\n\nSource: developers.akahu.nz — Personal Apps, App Accreditation, OAuth2 guides.\n\n### What we're on now\n\n**Personal App.** Akahu's stated limit: **1 user, restricted to your own Akahu\naccount.** Free. Daily scheduled refresh, 1-hour manual refresh rest period.\nRiley and Ella each have their own personal app and paste their own tokens.\n**This model cannot serve other people. There is no \"add users\" option.**\n\n### What public release requires: a Full App + Accreditation\n\nFour gates:\n\n1. **Privacy notice** covering data exchanged via Akahu.\n2. **Consumer information page** — what data, why, one-off vs ongoing, plus an\n accurate description of Akahu and their logo.\n3. **Security + penetration test** — grey-box pentest of the user-facing app and\n its APIs, by a competent firm. Real money (thousands). Only waivable if we\n hold SOC 2 / ISO 27001, which we don't.\n4. **Akahu application review** — free for the first review and the first re-check\n of fixes; **$1,000 per subsequent review**. Full apps are usage-priced, not free.\n\n### Where Stash currently FAILS their requirements\n\n- ❌ *\"Akahu credentials (App Secret and User Access Tokens) are not exposed to\n the client\"* — our entire connect flow is the user pasting a **user access\n token** into the client. This is exactly backwards. Needs the **OAuth2\n authorization-code flow**: redirect to Akahu → user picks accounts → we get a\n `code` → **server** exchanges it (within 60s) for the user token via `/token`\n with our App Secret. Must use the `state` param.\n- ❌ **Password strength** — 6 chars, no complexity. They require \"high quality\n strength requirements (minimum length & character variation)\".\n- ⚠️ **MFA** — required in general, BUT they explicitly say read-only apps may get\n relaxed requirements at their discretion (username + strong password is\n allowable). **Stash is read-only, no payments — ask them for this exemption.**\n- ⚠️ **Persistent sessions** — web sessions >2h must expire MFA status after 2h.\n Ours never expire at all.\n- ❌ **Consumer controls**, none of which we have:\n - show a summary of accounts connected via Akahu\n - let the user revoke access (`DELETE /authorisations/{id}` or `DELETE /token`)\n - revoke ALL access + delete their Akahu-derived data when they delete their\n Stash account (Privacy Act 2020: only retain data as long as reasonably needed)\n - handle the token being revoked externally — either the `TOKEN DELETE` webhook\n or by handling 401s from Akahu\n - alert the user when a connected account's `status` goes `INACTIVE`\n\n### NZ Privacy Act 2020\n\nOnce we hold strangers' financial data we're an \"agency\": need a privacy policy,\na breach-notification plan, and data deletion on revoke/account-deletion.\n\n---\n\n## 5. The three realistic paths\n\n1. **Friends-only, stay as-is.** Free, legitimate, works. Each person makes their\n own Akahu personal app and pastes tokens. Never leaves the circle of people who\n already trust Riley. Do the §3 cheap fixes anyway.\n2. **Build it properly, decide later.** Get a Full App in sandbox, build OAuth +\n consumer controls + strong auth, ask Akahu about the read-only MFA exemption.\n Only pay for the pentest if we actually commit to launching.\n3. **Public without banks.** Strangers get Stash in manual mode (no Akahu at all);\n the bank connection stays personal-app, for Riley and Ella only. Sidesteps\n accreditation entirely.\n\n**Note:** the reason Akahu demands all of the above is precisely the concern Riley\nraised unprompted. His instinct matched the regulatory bar.\n",[300],"786cd03a-4fd5-4294-b891-e2e58119c72c","BREACH_PLAN.md","019f5f53-c06b-7495-ad02-39995e39c63d",304,["D",1784010752114],"# Stash — privacy breach response plan\n\nInternal. Not served to users. Written 14 July 2026.\n\nThis exists so that the worst hour of this project is not also the hour you have to invent a\nprocess. Read it now, while nothing is on fire. The whole thing takes ten minutes.\n\n**Who runs this:** Riley. There is nobody else. That is a real weakness — see §7.\n\n---\n\n## 1. What a breach actually looks like here\n\nA privacy breach under the Privacy Act 2020 is unauthorised access to, disclosure of, alteration\nof, or **loss of** personal information. Loss counts. The data-loss incident on 13 July 2026 — where\na bad deploy overwrote a live account with junk — was, technically, a privacy breach affecting one\nperson who happened to be the operator.\n\nRealistic scenarios, roughly in order of likelihood:\n\n| # | Scenario | Is user data exposed? |\n|---|---|---|\n| 1 | A deploy bug destroys or corrupts user data | No, but data is **lost** — still a breach |\n| 2 | Val Town account compromised (password/token stolen) | See §2 — this is the bad one |\n| 3 | The SQLite database or blobs leak | Budget data is **ciphertext**. Usernames, hints, waitlist emails are not |\n| 4 | An access-control bug serves user A's blob to user B | Ciphertext, so B cannot read it — but it is still unauthorised disclosure |\n| 5 | A user's own password is guessed | Their data is exposed, to whoever guessed it |\n| 6 | Akahu tokens leak (only if Pro ever ships) | Yes, and badly. Bank transaction access |\n\n## 2. The one that matters: Val Town account compromise\n\nEncryption means a stolen *database* is close to harmless. It does **not** mean a stolen *account*\nis harmless, because whoever holds the Val Town login can **change the JavaScript that Stash serves**\nand capture passwords and plaintext from the next person who logs in.\n\nSo: **the Val Town login is the crown jewel, not the database.** Protect it accordingly —\nstrong unique password, 2FA on, and never paste the API token anywhere.\n\nIf you ever suspect it is compromised, that is a **live, ongoing** breach, not a historical one.\nTake the app offline first and ask questions second. Every minute it is up, it is harvesting.\n\n## 3. What to do, in order\n\n**Contain (minutes, not hours).**\n1. If the server may be serving malicious code: **take Stash offline.** A blank page beats a\n compromised one. Do this before investigating.\n2. Rotate: Val Town password + 2FA, `APP_KEY`, VAPID keys, Akahu tokens.\n3. Invalidate every session: `DELETE FROM mb_sessions`. Everyone gets logged out. Fine.\n4. Do **not** delete logs, blobs or backups. You will need them, and destroying evidence of a\n breach is its own problem.\n\n**Assess (same day).**\n5. What was taken or lost, whose, and when. Write it down as you go — memory is unreliable and you\n will be stressed.\n6. Ask the s.113 question honestly: **is serious harm likely?** Consider the sensitivity (this is\n financial data — treat it as sensitive), whether it was protected (encrypted budget = a strong\n mitigating factor; usernames, hints and waitlist emails = not protected), who has it, and whether\n it can still be misused. Do not talk yourself out of it because notifying is embarrassing.\n\n**Notify (as soon as practicable; target within 72 hours of deciding it is notifiable).**\n7. **Office of the Privacy Commissioner** via NotifyUs — \n You can notify while still investigating. Do not sit on it waiting for a complete picture.\n8. **Affected people.** See §4 — this is the gap.\n9. If Akahu is involved: tell Akahu immediately. It is their accreditation on the line too.\n\n**Fix and learn.**\n10. Patch the cause. Then write the postmortem into `SECURITY_NOTES.md`, including what let it\n happen. The gravestone comments in `index.html` exist for exactly this reason and they work.\n\n## 4. The hole: there is no way to email users\n\n**Stash does not collect email addresses.** That is good for privacy and bad for exactly one thing —\nthe Privacy Act obligation to notify affected individuals directly. Right now the only channels are:\n\n- a banner inside the app (only reaches people who open it),\n- a push notification (only people who turned them on),\n- a public notice on the site (s.116 allows public notice where individual notice is not reasonably\n practicable — this is the fallback, and it is a fallback, not a plan).\n\n**Recommendation:** add an *optional* email field at signup, used only for security notices. Say so\nplainly at the point of asking. It is a small privacy cost for a real ability to warn people that\ntheir money data is at risk. Until that exists, this plan cannot fully meet the notification duty,\nand the privacy policy says so honestly rather than pretending otherwise.\n\n## 5. Numbers to have to hand\n\n- Office of the Privacy Commissioner — 0800 803 909 — privacy.org.nz\n- NotifyUs (self-assessment + notification tool) — privacy.org.nz/responsibilities/privacy-breaches/notify-us/\n- Val Town support — for hosting-side incidents\n- Akahu support — only relevant if a bank feed is ever live\n- CERT NZ () — worth reporting an attack to, separate from the Privacy\n Commissioner\n\n## 6. What is already in place\n\n- Budget data is end-to-end encrypted; the server cannot read it, so a database leak is far less severe.\n- Nightly verified backups, 14-day retention, plus a permanently protected best-known copy, so\n scenario 1 is recoverable.\n- A shrink guard on `/api/state` that refuses a write which would collapse an account, plus rolling\n version history.\n- Rate limiting on login, signup and recovery.\n- Account deletion purges backups too, so \"delete\" means deleted.\n\n## 7. The honest weaknesses\n\n- **One person.** If Riley is asleep, on a plane, or ill, nothing in §3 happens. There is no\n on-call, no second pair of eyes, and no one to notice a breach at 2am.\n- **No monitoring or alerting.** Nothing would tell you a breach was under way. The backup job's\n size-drop alert is the only automated warning of anything, and it only catches data *loss*.\n- **No email channel to users** (§4).\n- **The operator serves the JavaScript.** This is the ceiling on the encryption and it cannot be\n fixed by policy.
