DRAFT for review · Last updated: August 20, 2026 · Operator details to be completed before launch.
The short version: we designed Guava so there is almost nothing to collect.
No account, no personal data. Bitcoin Guava requires no registration. We do not ask for your name, email, wallet, or identity. Calculator inputs and your preferences (theme, streak, push hour) are stored locally in your browser (localStorage) and never leave your device.
Push notifications. If you enable the morning push, your browser generates an anonymous push subscription (an endpoint URL and cryptographic keys) which we store together with your chosen hour, solely to deliver the daily notification. It contains no personal information. Disable the push at any time in Settings; the subscription is then deleted.
Server logs. Our server keeps standard, short-lived technical logs (IP address, user agent, requested URL) for security and abuse prevention, automatically rotated. We do not build profiles and we do not use third-party analytics trackers or advertising pixels.
Third-party data sources. Market data shown in the app is fetched by OUR server from public APIs (exchange market data, mempool.space, alternative.me). Your browser talks only to bitcoinguava.com — third parties never see your requests.
Legal basis & contact. Processing described above rests on legitimate interest (operating and securing the service). Operator: [LEGAL NAME / ADDRESS — to complete]. Contact: [EMAIL — to complete]. You may request information or deletion of push subscriptions at any time.
