Shmangus Privacy Policy
Last updated: 9 September 2026
Shmangus is a personal assistant app. This policy explains what it stores, where, and why — in plain terms. The short version: your data is yours, it is used only to run the features you use, it is never sold, and you can delete all of it at any time.
What we store
When you create an account and use the app, the following is stored on our server so it can sync across your devices and the website:
- Account — your email address, and a name/photo if you set one.
- Your content — reminders, notes, to-buy items, saved items, spending and transactions you add, custom apps, and anything you write in chats or the ideas doc.
- Messages — messages you send to other Shmangus users, and read/delivery status.
- Mail — if you claim a Shmangus email address, mail sent to it and any aliases you create.
- Your Claude API key — if you add one, it is stored encrypted at rest and used only to make requests to Anthropic on your behalf.
- Device push token — so reminders and messages can notify you.
- Health — what you log in the Health app: meals and the foods in them, workouts and the weights you lifted, weigh-ins, and the profile you set (goal, height, weight, training days). This is general wellness data you type, not medical records, and it is never used for advertising.
- Community — the communities you join, and what you post there: posts, replies, reactions and votes. Community posts are public to everyone who can see the room, under the name on your account.
- Spending — the transactions and budgets you add or import from a statement. A statement you import is read by the assistant to extract its transactions.
- Voice notes and call audio — a voice note you record is stored so the person you sent it to can play it. Call audio is sent between the two phones and is not recorded or stored.
- Credit — if you buy credit, what you were charged and what you used. Card details are handled by Stripe and never reach our server; we keep only Stripe's identifier for you.
- Error reports — when the app hits an uncaught error or freezes, it sends the error, the device model and the build number so it can be fixed.
What stays on your device
Passwords saved in the vault never leave your device — they live in the iOS Keychain and are unlocked with Face ID. They are not sent to our server or included in backups.
Third parties
- Anthropic (Claude) — when the assistant answers you, your message and relevant context are sent to Anthropic using your own API key, under Anthropic's privacy policy. Shmangus adds nothing to that beyond what you ask.
- Apple / Expo push services — used only to deliver notifications.
- Stripe — if you buy credit on the website, Stripe takes the payment. Card details go to Stripe, not to us.
- OpenStreetMap, Photon/Nominatim and the MTA — map tiles, address lookup and transit timetables for ShmangNav. A place you search and, if you allow it, your coordinates are sent to look them up.
- Resend — sends the sign-in code to your email address.
We do not sell your data, we do not run advertising, and we do not share your content with anyone except the services above needed to provide the features you use.
Location
ShmangNav, the trip planner, asks for your location only while you are using the app, and only so a trip can start from where you are. Naming a starting point instead works without it. When you use it, the coordinates go to our server to be turned into a place name and a route, and to OpenStreetMap's geocoder for the same reason. They are not stored and never used to track you. The app never asks for background or always-on location.
Contacts
The app reads a contact only at the moment you pick one to add as a friend. It does not upload your address book.
Deleting your data
You can delete your account from Settings → Delete account in the app or on the website. This permanently erases your account and everything stored for it on the server. Anything held only on your device is removed when you delete the app.
Children
Shmangus is not directed at children under 13 and we do not knowingly collect their data.
