Data Deletion
Short answer: there is nothing to delete, because nothing is collected.
Manila has no accounts and no server that stores user data. Your PDFs, photos and the files the app produces exist only on your own device.
How to remove everything Manila keeps
Uninstall the app. That removes the app's local storage — your language choice and interface preferences. (The app does not create a device or installation id, so there is no identifier to remove.) Files you saved or shared yourself stay where you put them; delete those from your Files app if you want them gone.
You can also clear the app's data without uninstalling: Android Settings → Apps → Manila → Storage → Clear data.
What about the subscription?
The subscription lives in your Google Play account, not in ours. Cancel it in Google Play → Payments and subscriptions → Subscriptions. We hold no billing record beyond what Google reports to the app while it is running.
Requests
If you still want written confirmation of what we hold about you, write to [email protected] and we will answer. The answer will be: nothing.
