The ten tiles with name, phone number and picture are stored only on this device. RamuPhone has no server, no account and no sign-in. No data is transferred to the provider or to third parties. An optional password for the setup screen is stored on the device as a PBKDF2 hash only, never in clear text.
The app contains no advertising, no analytics or tracking services and no advertising identifiers. No profiling takes place.
Contacts and photos are read only when you import an entry yourself. On iPhone this happens through the system picker, which hands the app a copy of the chosen contact; RamuPhone needs no contacts permission for that. On Android the read permission is requested and may be denied, free text entry still works. The call itself is handed to the device's phone app. There is no access to location, microphone, camera or health data.
You delete your data in the app or by uninstalling RamuPhone. As nothing is kept on a server, it is then gone completely.
You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21), and the right to lodge a complaint with a supervisory authority (Art. 77 GDPR). Please send requests to ds@ihanwel.net. As RamuPhone collects no data, the provider holds no personal data about you.
