Package net.cucp.calmemo · last updated 2026-11-13
Summary
Cal Memo does not run any server of its own and the developer does not receive your data. There are no ads, no analytics and no tracking.
Data the app handles
Your meal log, foods, water, weight entries, progress photos and profile (sex, age, height, weight, goal) are stored only on your phone. The developer runs no server and receives nothing; there are no ads, analytics or tracking SDKs.
When you tap Analyse, the meal photo (downscaled) or the meal text you typed or spoke is sent over HTTPS directly to the AI provider you connected with your own API key (Google Gemini, OpenRouter, Groq, OpenAI, Anthropic or xAI). That provider's privacy terms apply; free tiers may use submissions to improve their models. Your API keys stay encrypted on the phone.
Barcode scans use Google's code scanner in Google Play services; the barcode number or product search text is sent to Open Food Facts to look up nutrition.
Voice input uses Android's speech recognizer; the app only receives the text.
Optional backup and sync to the hidden app-data folder of your own Google Drive (scope drive.appdata). The developer has no access to it.
An optional PIN is stored only as a salted hash; Android cloud backup is turned off for this app. Calorie numbers are estimates, not medical advice.
Purchases
The app can be used free for 7 days. After that, a one-time purchase unlocks it. Payment is handled entirely by Google Play; the developer never sees your payment details.
Deleting your data
Uninstall the app or clear its data to remove everything on the phone. Remove the Drive copy in Google Drive → Settings → Manage apps → Cal Memo → Delete hidden app data.
