Fossy Protokoll

Fossy Protokoll Document Scanning app for Android description

Fossy Protokoll helps tenants in Germany keep a verifiable record of defects in their flat: noise disturbance, mould, heating failures and more.

From the recorded occurrences it builds a protocol covering a chosen period, and a factual defect notification addressed to the landlord. Both can be saved and shared as PDF or Markdown.

The interface and all generated documents are written in German, because they follow German residential tenancy practice.

The app documents, it does not advise. The generated texts cite no statutes, claim no rent reduction and set no deadline of their own. A response date only appears when you enter one yourself.

Data lives in a local database, photos in the app's private directory. The app requests no permission that touches your data or the device, never accesses the network, and contains no tracking or analytics. When you export something, you choose the destination yourself.

Android's automatic backup is switched off as well, so your defects and photos never reach a cloud account. Instead you can create a full backup as a ZIP file at any time and restore it later, for instance when moving to a new phone. Without such a backup the data is lost if the device is.
