Private, offline-first health records · iPhone & Android
DiaKeep: private health records on your phone — no cloud account
Your health records. Your phone. Your control.
Tired of cloud PHRs that demand another account, or a spreadsheet that never fits in your pocket? DiaKeep is a personal health record companion that keeps glucose readings, medications, lab results, appointments, and report photos organized on the device you already carry.
No DiaKeep account · No cloud health database · No ads · No tracking · Encrypted on-device · One-time purchase
Available for iPhone and Android · One-time purchase · No DiaKeep subscription
Your health records shouldn’t live in five different places.
Paper in a drawer. Readings in a sheet. Meds in Notes. Appointments in a calendar. Screenshots in camera roll. Cloud PHRs solve some of that by making you create yet another login, and shipping your history to someone else’s servers.
DiaKeep gives those records one private home on your phone. Offline-first. Built for people who want history with them, not another account to manage.
Health details, organized around real life.
Glucose
Log readings with context: fasting, before or after meals, bedtime, exercise, and more. Use mg/dL or mmol/L. See your history over time without exporting to a spreadsheet first.
Medications
Keep names, doses, and schedules together, with adherence tracking so you can see what you recorded.
Labs
Record HbA1c and other lab results, enter the reference range shown on your own lab report, and build a lab history you can actually browse later.
Appointments
Keep visits, locations, and specialties together. Optional calendar mirroring, with the choice to send only a generic “Medical appointment” entry instead of the details.
Report photos
Attach photos of printed lab reports so the source stays with the result. Photos live in DiaKeep’s encrypted local database and are not automatically saved to your photo gallery.
Backup & transfer
Export and import local records when you want a backup or need to move to another phone.
A note about exported files: records inside DiaKeep are protected in the app’s encrypted local database. Exported files are not encrypted by DiaKeep, so store and share them carefully.
Private by design. Not as an afterthought.
