SnapCal turns a photo of a math problem into a step-by-step solution. It has no servers of its own — here's exactly where a photo goes, and what stays on your phone.
✕ No accounts Nothing to sign up for, no login
✕ No analytics or ads Nothing tracked, nothing sold
✕ No SnapCal servers Your device talks directly to your chosen AI provider
Photos leave your device Only to the AI provider you pick, to be solved
Photos of math problems. When you take or choose a photo, it's resized on your device and sent directly to the AI provider you've selected in Settings, so it can read and solve the problem. SnapCal doesn't keep a copy anywhere except your phone's local app storage, and doesn't see the photo pass through any server of ours — there isn't one.
Your API key. Each provider's key is stored in EncryptedSharedPreferences on your device. It's sent only in the authentication header of requests to that same provider's API — never anywhere else, never to us.
SnapCal supports four providers. Only the one you've selected in Settings ever receives anything, and only for the problem you just photographed:
DeepSeek — api.deepseek.comOpenAI — api.openai.comAnthropic — api.anthropic.comGoogle — generativelanguage.googleapis.com
That provider processes the image under its own privacy policy and terms — SnapCal has no control over, and receives no data back from, how long they retain it. If you switch providers in Settings, only future photos go to the new one.
SnapCal also supports picking an existing photo from your gallery instead of using the camera, via Android's standard photo picker.
SnapCal isn't directed at children and doesn't knowingly collect data from anyone. Because solving a photographed problem requires sending it to a third-party AI provider, a parent or guardian should decide whether that's appropriate before a child uses this app.
