WHY LUNA IS DIFFERENT
Most period apps sell your data or run ads. Luna operates 100% offline. Your intimate records live in your device's secure sandbox—we cannot sell, share, or lose what we never had.

Comments on Luna - Private Period Tracker for Android
★★★★★Shahanaz Khatun· Jul 8, 2026
It's a completely private period tracker, no account or login needed. Everything stays on my phone. In a market where almost every tracker wants your email address just to sell your cycle history to advertisers, this offline cycle tracker is a breath of fresh air. The layout is clean and simple. Since there is no servers, I don't have to worry about data leaks. Keep up the solid work, mate!
★★★★★tapash karmaker· Jul 7, 2026
Tried so many cycle trackers to keep my partner in the loop, but hated how they all force you to link online accounts. Felt super invasive. Luna solved this completely with the partner share feature. I just showed him a QR code on my screen, he scanned it, and now his app updates offline. No servers, no ads, and he doesn't see my private logs or notes. Genuinely the best couples period tracker.
