Most apps ask you to trust their privacy promise. We would rather you check it. Everything below is something you can verify yourself, without taking our word for anything.
Turn on airplane mode
Put your phone in airplane mode and open Her Almanac. Record a symptom, write a journal entry, add an appointment. Everything works. Nothing can be sent anywhere, because there is nowhere for it to go. The app has no server to reach even when it has a connection.
Watch the network yourself
If you know how to capture your phone's network traffic, do it while you use the app. You will see the app make no network requests at all, ever. On Android, it does not hold the internet permission, which you can confirm for yourself in your phone's app settings or with any manifest viewer: an app without that permission cannot open a connection even if its code tried. On iPhone, turn on App Privacy Report (Settings, then Privacy & Security, then App Privacy Report) and use the app for a day: Her Almanac will not appear under App Network Activity, because it contacts nothing. The network footprint of the app is zero.
Read the code paths we describe
Our privacy policy describes what the app does in plain terms, and our in-app Privacy and Security screen lists exactly what is stored and what is deleted. If you ever find a place where our words and our app disagree, that is a bug we want to fix, and we would rather hear it from you than have it be true.
Tell us what you find
Email hello@heralmanac.app with anything that does not match what we claim. We keep a dated public archive of every version of our policies, so you can always check what we said and when. Verification is the whole point. We built the app so that checking is possible on purpose.
