Doselane

Privacy Policy

Last updated: 31 October 2026

Doselane keeps your health records on your iPhone. There are no accounts, no servers of ours and no tracking.

The short version

Doselane does not collect, transmit, sell or share your personal information. We have no servers that receive your data, and we have no way to see it.

Data you enter

Your medicine, doses, shot dates and times, dosing schedule, injection sites, side effects, appetite, protein, fiber and water, protein favorites, weight, goals, pen stock, progress photos, notes and settings are stored on your device, in Apple's on-device database. Doselane's widgets and Live Activity read the same on-device store. None of it leaves your device through Doselane.

Progress photos you add are kept inside Doselane only: they are not saved to your photo library and never leave your iPhone unless you share them yourself.

This is health information. We treat it with that care by not holding it at all.

Apple Health

Connecting Apple Health is optional, and you choose each data type in Apple's own permission screen. If you allow it:

• Doselane reads your weight, body fat percentage, lean body mass, BMI, waist circumference, height, dietary protein, dietary fiber and water, to show them next to your dose weeks and on the Progress screen.
• Doselane writes the side effects and appetite you log (nausea, constipation, diarrhea, heartburn, tiredness, headache, appetite changes), the water you log and any weight you type in, so they appear in the Health app too.

Data read from Apple Health is used only inside the app to show you your own records. It is never used for advertising or marketing, never sold, never shared with third parties and never sent to us. You can change or withdraw access at any time in iPhone Settings › Health › Data Access & Devices › Doselane.

Reminders

Shot-day reminders are local notifications scheduled on your iPhone. No push server is involved.

Exports

When you share the doctor report (PDF) or your records (CSV), the file is created on your iPhone and goes only where you send it from the share sheet: an email, Files, a message, a printer. What happens to it there is up to you and that service.

Analytics and tracking

Doselane contains no analytics, no advertising and no tracking. It uses no cookies, no advertising identifiers and no third-party services that would profile you.

Purchases

Doselane Pro (monthly, yearly or lifetime) is sold and processed by Apple through the App Store. Apple handles your payment details; we never see them. Data about your purchase is governed by Apple's Privacy Policy.

Your data, your control

• Edit or delete any entry at any time.
• Export your records as CSV at any time, with or without Pro.
• Deleting the app deletes everything Doselane stored on your device. Samples Doselane wrote to Apple Health stay in Health until you delete them there. We hold no copy, so we can't restore anything.

Your rights

If you live in the European Economic Area or the United Kingdom, the GDPR gives you rights to access, correct and delete your personal data. Because Doselane holds no data about you on any server, you exercise these rights directly on your device, as described above. You can always contact us with questions.

This website

These pages use no cookies and no analytics.

Children

Doselane is not directed at children under 13. We collect no data, so we do not knowingly collect information from anyone.

Changes to this policy

If this policy changes, the new version will be posted here with a new date. Because Doselane doesn't collect your contact details, we can't email you; this page is the single source of truth.
