Tefilah
A private record of davening.
You only type this once on this phone. After that you tap your name and use your own four digit PIN.
What this app keeps
What you davened, your own notes, the names you want to daven for, and yahrzeit dates. Nothing leaves this server, nothing is sent anywhere, and the page is not listed on any search engine.
What you logged is yours alone. There is no screen anywhere in the app that shows somebody else what you davened, and there is no setting that would turn one on. The only thing that can be shared is a note you share yourself, one at a time.
