Privacy Policy

What we collect, why, and what you can do about it.

This policy describes the behaviour of this software as built. It has not been reviewed by a lawyer — have counsel review it before relying on it.

What we do NOT collect

Cookies

Two, both strictly functional — no advertising or tracking cookies:

Third parties

Serving a page makes server-side requests to the public data providers listed on the About page. Those providers see our server's requests, not your IP address or identity. Fonts and two JavaScript libraries load from fonts.googleapis.com, cdn.jsdelivr.net and cdnjs.cloudflare.com, which will see your IP as part of normal browser requests.

Your rights

You can access, correct, export or delete your data. Account deletion removes your email, credentials, watchlists, tracked wallets, alert rules and portfolio entries; billing records may be retained where law requires. To exercise any of these, email not published yet.

Depending on where you live (e.g. the EU/EEA under GDPR, or California under CCPA) you may have additional rights, including objecting to processing and lodging a complaint with your data protection authority.

Security

Passwords are scrypt-hashed. Session tokens are signed JWTs delivered in httpOnly cookies. Access to your saved data is scoped to your account. No system is perfectly secure; if you find a vulnerability, please report it to not published yet rather than disclosing it publicly.

Changes

Material changes to this policy will be announced in-app before taking effect.
