The app has no multi-tenancy: one val is one\nperson's subscriptions. The two instances share code and nothing else — separate\ndatabases, separate email addresses, separate dashboards. Verified: a row written\nhere is not visible in the original.\n\nKeep them in sync by re-applying code changes to both, or by remixing again.\n\n## Before it works — what to set\n\nEnvironment variables live under **Settings → Environment variables** on this val.\n\n| Variable | Status | Value |\n|---|---|---|\n| `ANTHROPIC_API_KEY` | **set** | A key dedicated to this instance. Verified working: it extracts subscriptions from forwarded receipts and answers emailed questions. |\n| `ALLOWED_USERS` | **needed** | The colleague's Val Town handle. Without it they get a 403. Alternative: add them to the `xdv` org, which the gate also accepts. |\n| `DIGEST_EMAIL` | optional | **The colleague's own address**, so their digest goes to them and not to the owner of the other instance. While empty the cron runs and skips sending. |\n| `BASE_CURRENCY` | optional | Defaults to `PLN`. `USD` and `EUR` also supported. |\n| `APP_URL` | not needed | The val resolves its own endpoint at runtime, so email links work without it. Override only for a custom domain. |\n\n## This instance\n\n- Dashboard: https://xdv--01a05e913c61747c96e4e7f8845199ec.web.val.run\n- Forward receipts to: `xdv-01a05e913c61747c96e4e2c7a9706763@valtown.email`\n- Daily digest: 06:00 UTC, and only when there is something to say\n\n---\n\n\nA Val Town app for deciding, month by month, whether each subscription is still\nworth paying for. Three parts: a schema that keeps enough history to answer\n\"what did cancelling save me\", an email assistant you forward receipts to, and a\ndashboard.\n\n## What it answers\n\n| Question | Where |\n|---|---|\n| What do my subscriptions cost me a month? | Run rate — every yearly plan divided by twelve |\n| What leaves my account in March? | 12-month calendar forecast, yearly renewals marked separately |\n| Which ones should I drop? | Two grades a month (quality, usage) → a keep/watch/cancel verdict |\n| What has cancelling saved me? | Monthly equivalent of each cancelled plan, counted from the day it stopped |\n| What do I need to decide right now? | The decision inbox — renewals you can still stop, ratings due, cancel candidates |\n\nRun rate and the calendar forecast are deliberately separate numbers. Averaging a\nyearly plan into a monthly figure makes it comparable; it also hides the month the\nmoney actually leaves, which is the surprise worth avoiding.\n\n## Files\n\n```\nindex.ts HTTP: the dashboard and its JSON API (fileType: http)\nemail.ts inbound mail: forward receipts here (fileType: email)\ncron.ts daily: FX, decision inbox, digest (fileType: interval, 0 6 * * *)\n\nshared/ types, money and date maths, verdicts, forecasting — pure, runs on both sides\nbackend/ db schema, FX, queries, analytics, review inbox, LLM, email handling\nfrontend/ the React dashboard (no build step; Val Town transpiles per request)\ntests/ the pure logic, run with `deno test --allow-import tests/`\n```\n\n## The schema\n\n`services` — the vendor. `subscriptions` — one billing arrangement for a service;\na service can own several over time as plans and prices change, but only one is\nlive. `charges` — payments that really happened. Nothing in the future is stored:\nit is projected from `next_charge_on`, so a price change never leaves stale rows\nbehind.\n\n```\nservices id, name, name_key(unique), vendor_domain, category, notes\nsubscriptions id, service_id, plan_name, amount_minor, currency, billing_cycle,\n started_on, next_charge_on, status, cancelled_on, cancel_reason,\n payment_method, auto_renew, source, notes\ncharges id, subscription_id, charged_on, amount_minor, currency,\n base_minor, fx_rate, source, inbound_email_id\nratings id, subscription_id, period(YYYY-MM), quality 1-5, usage 1-5, note\n unique(subscription_id, period)\nreview_items id, subscription_id, kind, status, title, detail, due_on, dedupe_key\ninbound_emails id, message_id(unique), from_addr, subject, body, intent, handled, result\nfx_rates quote, base, rate, as_of\nsettings key, value\n```\n\nMoney is stored as **integer minor units** (grosze, cents) in the currency it is\nactually billed in — never a float, never pre-converted. Conversion to your base\ncurrency happens at read time, except on `charges`, which pin the rate that applied\non the day so history is not re-priced when the zloty moves.\n\n`status` is `active | trial | paused | cancelled`. Cancelling keeps the row: the\nprice and the stop date are exactly what the savings figure is computed from.\n\n## The verdict\n\nEach month, two grades out of five: **quality** (how good is it) and **usage** (how\noften do you reach for it). They are combined with a harmonic mean, which collapses\ntoward whichever is worse — 5 and 1 give 1.7, not 3. A brilliant tool you opened\ntwice is still money leaving.\n\nRatings are recency-weighted over six months (each month back counts 0.75 of the\none after it), so one quiet month nudges the score without flipping it. Bands:\n`>= 3.5` keep, `>= 2.5` watch, below that a cancel candidate. A *watch* that costs\nmore than your median subscription is promoted to a cancel candidate — an\nabove-median price only has to be middling to deserve a decision.\n\n## The email assistant\n\nForward mail to the address Val Town assigns `email.ts` (read it from `links.email`\non the file listing — never construct it).\n\n- **Forward a receipt with nothing on top** → it is extracted and tracked, and a\n *confirm* item appears in the decision inbox. Nothing is ever written silently.\n- **Forward it with a question on top** → both: the charge is recorded *and* the\n question is answered from your data.\n- **Send a command** as the first line:\n\n```\nlist active subscriptions and run rate\nforecast [months] calendar forecast, yearly renewals marked\nupcoming [days] what is due soon\nsavings what cancelling has saved you\nreview the decisions waiting on you\nrate 4 2 quality 4, usage 2, for this month\ncancel [because …]\nkeep clear its open decisions\nadd 49.99 PLN monthly\nhelp\n```\n\nAnything else is treated as a question and answered by the model from your\nsubscription data.\n\nExtraction uses a strict tool rather than a forced one: a receipt the model cannot\nread comes back as \"no result\" instead of a confidently wrong row. Without an API\nkey the app still works — receipts fall back to a text scan that takes the largest\nmoney amount, and commands are unaffected.\n\n## Environment variables\n\n| Variable | Required | What it does |\n|---|---|---|\n| `ANTHROPIC_API_KEY` | for the assistant | Receipt extraction and email Q&A. Without it, commands and the heuristic scan still work. |\n| `APP_URL` | no | Overrides the dashboard link in emails. Leave unset — the val asks the platform for its own endpoint, so a remixed copy links to itself with no setup. Set it only for a custom domain or a proxy. |\n| `BASE_CURRENCY` | no | `PLN` (default), `USD` or `EUR`. Everything rolls up into this. |\n| `ALLOWED_USERS` | no | Extra Val Town handles allowed in, comma-separated. Members of the owning org always get in. |\n\nFX rates come from Frankfurter (ECB reference rates, no key), cached daily, falling\nback to the last cached value.\n\n## Who can see it\n\nThe dashboard is spending data, so the endpoint is not open. Val Town's\nplatform-level restricted access needs a paid business org, so the gate lives in\nthe val instead: `std/oauth` wraps the whole app, and a visitor gets through only\nif they are signed in to Val Town **and** belong to the org that owns this val.\nAnyone else gets a 401 (API) or a 403 page (browser) — never the data. Add\nindividual handles with `ALLOWED_USERS` if someone outside the org needs in.\n\nIf this val ever moves to a business-tier org, `set_http_privacy: restricted` is\nthe better mechanism — it gates at the platform edge, before any code runs — and\nthe `oauthMiddleware` wrapper should come off at the same time so nobody has to\nauthenticate twice.\n\n## Deploying\n\nThe val needs three file types: `index.ts` as `http`, `email.ts` as `email`,\n`cron.ts` as `interval` with `0 6 * * *` (UTC — that is 07:00 or 08:00 Warsaw\ndepending on the season; cron does not follow daylight saving).\n\nNo post-deploy URL configuration is needed: `backend/links.ts` resolves this val's\nown endpoint at runtime via `httpEndpoint()` from `std/utils`, so a fresh remix\nlinks to itself. `APP_URL` remains available as an override.\n\n## Not built yet\n\nGoogle Calendar entries for upcoming renewals, and bank feeds via bkpr to\nreconcile charges against what actually left the account.\n",[],[116],"89c69a17-3e9f-482c-a4e5-69fcbef71e4c","tests","01a05e91-3c61-747c-96e4-d728b6f47ece",1,["D",1788292971385],0,"directory",[132,133,134,135,136],[124],{"_36":165,"_13":166,"_61":167,"_63":125,"_65":66,"_67":126,"_68":69,"_38":168,"_17":128,"_72":73,"_74":169,"_76":51,"_77":-5,"_96":170,"_18":171},{"_36":158,"_13":159,"_61":160,"_63":125,"_65":66,"_67":126,"_68":69,"_38":161,"_17":128,"_72":73,"_74":162,"_76":51,"_77":-5,"_96":163,"_18":164},{"_36":151,"_13":152,"_61":153,"_63":125,"_65":66,"_67":126,"_68":69,"_38":154,"_17":128,"_72":73,"_74":155,"_76":51,"_77":-5,"_96":156,"_18":157},{"_36":144,"_13":145,"_61":146,"_63":125,"_65":66,"_67":126,"_68":69,"_38":147,"_17":128,"_72":73,"_74":148,"_76":51,"_77":-5,"_96":149,"_18":150},{"_36":137,"_13":138,"_61":139,"_63":125,"_65":66,"_67":126,"_68":69,"_38":140,"_17":128,"_72":73,"_74":141,"_76":51,"_77":-5,"_96":142,"_18":143},"fba4138c-ffe4-4991-91eb-8144251bbd09","money_test.ts","01a05e91-3c61-747c-96e4-d206c5aa558e",["D",1788292971385],"import
