Needed for the Google Play listing.

  • /delete-account: public page with the steps to delete an account (app and web) and what is deleted or kept. Play's data safety form requires a public URL and rejects 404s.
  • Review login: REVIEW_LOGIN_EMAIL + REVIEW_LOGIN_CODE (optional env). Requesting a code for that one address sends no email and stores the fixed code; verifying goes through the normal path, so expiry, single use and the 5-attempt limit still apply. Play and App Store reviewers can't receive our emails or use their own accounts.
  • Test: reviewLogin.integration.test.ts (fixed code works once, only after requesting, only for that address).

Checks: tsc, lint clean; 312 tests pass.

Summary by CodeRabbit

  • New Features
    • Added a public account-deletion page with instructions for deleting an account through the app or website. It explains which data is removed, which shared data remains, and what happens to groups. A contact email is shown when one is configured.
    • Configured review sign-ins can use a fixed verification code without sending an email. Standard code expiry and attempt limits still apply. Other sign-ins continue to receive codes by email.

…iewers

/delete-account explains how to delete a SplitPro account in the app or on
the web and what is deleted or kept, as Google Play requires a public URL.

REVIEW_LOGIN_EMAIL/REVIEW_LOGIN_CODE let App Store and Play reviewers sign in:
requesting a code for that address sends no email and stores the fixed code,
then the normal verify path (expiry, single use, attempt limits) applies.

Walkthrough

The PR adds optional review-login settings and a fixed-code sign-in path for a configured email. It also adds a public account deletion page with deletion instructions, data handling details, and a conditional contact email.

Changes: Review login

Layer / File(s) Summary
Configure and verify review login
src/env.js, src/server/mobileAuth.ts, src/tests/reviewLogin.integration.test.ts
The environment schema and mapping add optional review-login settings. For a matching email, sendEmailCode stores a hashed configured code with the standard expiration and skips email delivery. The integration test checks sign-in and rejection cases.

Account deletion page

Layer / File(s) Summary
Publish account deletion instructions

The page explains deletion steps through the app and website, describes data deleted and retained, and displays a contact email only when one is configured.

The mobile reviewer flow is implemented, but web sign-in still emails a random code, configured codes lack documented format validation, and deletion guidance overstates when groups disappear. These are bounded issues suitable for correction or explicit owner follow-up.

Nitpick Check that the fixed code fails before any request.

35-38: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Check that the fixed code fails before any request.

Each run calls sendEmailCode before the first verifyEmailCode. The only check labeled "Without a requested code" runs after the code is consumed, so it repeats the reuse check above it. No assertion covers the fixed code before a request. An implementation that accepts RV7K2M before any request, but still rejects reuse, would pass this test.

Add a rejection check before the request:

🧪 Suggested fix
+      // Before any request, the fixed code is rejected
+      await assert.rejects(verifyEmailCode(reviewEmail, 'RV7K2M', `ip-${suffix}`), /Invalid/);
       await sendEmailCode(reviewEmail, `ip-${suffix}`);

Add a rejection assertion for verifyEmailCode with the fixed code before the
first sendEmailCode call in the test, so it verifies the code is invalid before
any request; retain the existing post-request and reuse checks.
Nitpick Cover the fixed code for non-review addresses.

40-43: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Cover the fixed code for non-review addresses.

The otherEmail check never requests a code, so it finds no stored token and rejects. A regression that stores RV7K2M for every requested address would still pass this check. Request a code for otherEmail before the check. Run that request with NODE_ENV set to development, so the mailer returns before it sends.

Suggested fix
-      // Other addresses never accept it
-      await db.verificationToken.deleteMany({ where: { identifier: otherEmail } });
+      // Other addresses reject the fixed code, even after they request a code
+      await db.verificationToken.deleteMany({ where: { identifier: otherEmail } });
+      mutableEnv.NODE_ENV = 'development';
+      await sendEmailCode(otherEmail, `ip-${suffix}`);
+      mutableEnv.NODE_ENV = 'production';
       await assert.rejects(verifyEmailCode(otherEmail, 'RV7K2M', `ip-${suffix}`), /Invalid/);

The delete must run before the request. Otherwise it removes the token that the request creates.

Update the otherEmail check around verifyEmailCode to request a code for
otherEmail before verifying the fixed code, keeping the token deletion before
the request. Run the request with NODE_ENV set to development so the mailer does
not send, then restore the prior environment before asserting that verification
rejects the fixed code.

Validate REVIEW_LOGIN_CODE against the sign-in code alphabet at startup.

The comment above REVIEW_LOGIN_CODE documents a six-character code from the sign-in code alphabet. The schema accepts any string, so a value of the wrong length, or one with characters outside that alphabet, starts without an error. The schema should enforce the documented format.

The sign-in alphabet is ABCDEFGHJKLMNPQRSTUVWXYZ23456789. It excludes 0, 1, I, and O, so [A-Za-z0-9] is too broad. The sending path at src/server/mobileAuth.ts:278 trims and uppercases the value, so the schema uses the same normalization, with a case-insensitive match.

Correct the deletion copy for groups that keep unsettled balances.

The page says a group is "deleted if nobody else is in them." The code deletes such a group only when it has no unsettled balance. A group whose other members have all deleted their accounts, and which still has an unsettled balance, is kept with the deleted account as its owner. Change the sentence to state the balance condition:

Apply the review-login code contract to the web email sign-in path.

When EMAIL_SERVER_HOST is set, the NextAuth EmailProvider in src/server/auth.ts handles every email sign-in request, including requests for REVIEW_LOGIN_EMAIL. Its generateVerificationToken returns a random token, and sendVerificationRequest emails it without checking the configured address. The REVIEW_LOGIN_EMAIL comment in src/env.js says that requesting a code for that address sends nothing and that the code is always REVIEW_LOGIN_CODE. The web path does not follow this contract. The web callback at /api/auth/callback/email accepts only the stored token, so REVIEW_LOGIN_CODE cannot complete a sign-in on this path.

Only the mobile sendEmailCode path in src/server/mobileAuth.ts implements the fixed code. Either this path must apply the same exception, or the src/env.js comment must state that the exception covers only the mobile endpoint.
