About

The same standard in every app.

BM Labs is the name Berat Mehmetoglu publishes iPhone apps under. Every app is built to the same standard: do one thing completely, open ready to use without an account, and keep what it holds on the device.

Data is stored on your iPhone. Where sync is offered it runs through your own iCloud account. One third-party dependency exists across the portfolio — Mapbox, which renders Tern's map — and Tern's privacy policy states it plainly. Nothing else is fetched, measured or sent anywhere.

Every app exports its complete contents in a format other software can read, so nothing is lost if an app is ever discontinued. Support is answered by the person who wrote it.
