Get help with PlainHygiene — an offline hygiene reference app.
PlainHygiene is a native, offline-first hygiene reference app for iOS and Android. It covers 1,088 sourced hygiene features across 18 modules — handwashing, menstrual and reproductive hygiene, food safety, body and personal hygiene, sanitation, life-stage hygiene, disease prevention, disaster/low-water hygiene, and more — plus routine-building and habit tools. It works with no signal, is privacy-first with no account and no tracking, and offers a generous free tier alongside an optional Pro subscription. PlainHygiene is live now on the App Store and on Google Play.
Yes — download PlainHygiene on the App Store for iPhone and iPad, or on Google Play for Android.
Yes. All 1,088 hygiene guides, search, and routine-building tools are bundled with the app and work fully offline, with no account required.
Yes. PlainHygiene is designed local-first, with no account required and no tracking. See our Privacy Policy for full details, including how the Pro subscription is handled by Apple/Google.
No. PlainHygiene provides educational hygiene guidance sourced from public-health authorities (WHO, CDC, UNICEF/JMP, and others), not medical diagnosis or treatment. If you think you may have a medical emergency, contact your local emergency services immediately.
PlainHygiene's free tier covers the core hygiene reference layer. PlainHygiene Pro is an optional, auto-renewing monthly subscription that unlocks additional depth. There is no one-time purchase option and no ads on either tier.
No. Your device caches your entitlement locally, and the App Store or Google Play — not any server PlainHygiene operates — handles renewal in the background. PlainHygiene itself runs no server for either the free or paid tier; the only network calls the app can ever make are an optional, off-by-default sync of public WHO/World Bank statistics, never your personal data.
PlainHygiene ships with multiple translated locales alongside English. Specific launch languages will be confirmed closer to release.
