Bleed keeps your cycle data on your phone and nowhere else. No servers. No accounts. No ads. No data collection. Not even a little. Bleed exist because other trackers treat your period like data to sell. Bleed doesn't. Everything stays on your phone, there's no signup, no paywall. You still get the useful bits: analytics that show your actual patterns, and a doctor's report you can export for appointments. Nobody's gossiping about you to advertisers, no in-app ads, and no in-app brand pushing. - Track your period, symptoms, moods, and notes, all on your device - Cycle predictions that get smarter the more you use it - Passcode and biometric lock - Exportable doctors report that contains your full picture - Analytics that show what your body actually does Privacy that's not a marketing line. We don't collect your data. Not encrypted on a server, not "anonymised," not in the cloud. We physically cannot see what you log. Hard to breach a server we don't have. After Roe v. Wade, people deleted their period trackers. We built Bleed so you'd never have to make that choice. Bleed is for every life stage: puberty, perimenopause, and everything in-between. Whether you're tracking your first period or your last one, whether you have irregular or clockwork cycles, whether you're trying to conceive or just trying to remember when your last period started. Bleed freely. Bleed privately. Period.
