Privacy Policy
MoonChart — AI Chart Detector · Last updated 31 October 2026
This policy explains what MoonChart collects, why, and who it is shared with. MoonChart contains no advertising, no analytics SDKs and no third-party trackers, and does not track you across other apps or websites.
Who is responsible
MoonChart is operated by lab1.bio. For any privacy question or request, contact support@moonchart.app.
What we collect
| Data | Why |
|---|---|
| A random identifier the app creates on your device | To keep your watchlist, alerts and history without asking you to sign in. It is not linked to your name or Apple ID. |
| If you choose to sign in with Apple (optional): your Apple account identifier, and the name and email address you choose to share | To sync your data across your devices. If you use Apple's private relay address, we only ever see the relay address. |
| Your watchlist, price alerts and briefing preferences | To show your markets and send the alerts you configure. |
| Chart analyses you create, including the market data analysed and the result | To show your analysis history. |
| Screenshots or photos of charts you choose to analyse | To produce the analysis you requested. See “AI processing” below. |
| Your subscription status | To unlock paid features. Payment details are handled by Apple and never reach us. |
We do not collect your location, contacts, browsing history or advertising identifiers, and we do not build advertising profiles.
AI processing
When you request an analysis, the relevant market data (price history and indicators for the asset) — and, if you analyse a photo or screenshot, that image — is sent to Anthropic, PBC's Claude API to generate the result. No account data (name, email or Apple account identifier) is sent to Anthropic. Before your first analysis the app explains what is sent and to whom, and asks for your permission; nothing is sent unless you allow it. You can withdraw permission at any time under Settings → Privacy.
Anthropic processes this data as our processor, solely to return the analysis, under its Commercial Terms and Data Processing Addendum (including the EU Standard Contractual Clauses), which protect it at least as strongly as this policy. Anthropic does not use it to train its models and deletes it within 30 days, unless it must keep it longer to enforce its usage policy or to comply with the law. Uploaded images are not stored on our server: only the resulting analysis is kept in your history, and a thumbnail of the image is kept on your device. Do not upload images containing personal information you do not want processed this way.
Face data
MoonChart does not collect, detect, analyse, store or share face data. The app uses no face recognition, Face ID, TrueDepth or face-tracking features. The camera and photo picker are used only to capture charts for analysis.
Who else receives data
- Apple — sign-in and all subscription payments and billing.
- Anthropic — chart analysis, as described above.
- Market data providers (CoinGecko, Binance, Twelve Data, Yahoo Finance) — these receive only the asset symbols being displayed. They receive no account data and no personal information.
We do not sell your data, and we do not share it for advertising.
Where data is stored
Account data is stored on our server in Germany, operated by Hetzner Online GmbH. Your analysis history is also kept on your device.
How long we keep it
Your data is kept while your account exists. Deleting your account deletes it.
Deleting your account
Open Settings → Delete account in the app. This permanently deletes your account and all associated data — watchlist, alerts, briefing preferences, analyses and stories — from our server, and removes the analyses stored on your device. It cannot be undone. You can also email support@moonchart.app to request deletion.
Your rights
Under the GDPR and comparable laws you may request access to your data, correction, deletion, restriction of processing, or a copy in portable form, and you may object to processing. Write to support@moonchart.app and we will respond within 30 days. You also have the right to complain to your local data protection authority.
Children
MoonChart is not directed at children under 13, and we do not knowingly collect their data.
Changes
If this policy changes materially we will update this page and the date above, and note it in the app.
