Privacy Policy
Dosenna is made by Cassian Vire, the publishing name of Amangeldy Baiserkeev, an individual developer (“I”, “me”). This policy explains what the app does with your data. Health information is personal, so the app is built to keep it with you.

The short version
Dosenna has no accounts, no advertising and no tracking. Your medications, doses, weight and notes are stored on your device and, if you use iCloud, in your private iCloud account. I cannot see your health data; only text or photos you choose to process with an AI feature are sent for processing and are not stored. To sell Dosenna Pro, the app uses Apple’s App Store and the Adapty subscription service, which receive a random app identifier and your purchase history, never your health data.
What you enter and where it is stored
The app keeps the following:
- your medications and the schedule your doctor prescribed;
- doses you log, with time, dose, injection site and notes;
- weight entries and your weight goal, if you set one;
- how you feel (side effects and wellbeing scores), if you log them;
- your settings, such as units, reminders and appearance.
This data is stored on your device. If iCloud is turned on for your Apple Account, it is also synced through your private iCloud database so it appears on your other devices and survives reinstalling the app. iCloud data is handled by Apple under Apple’s privacy policy; I cannot access it. A small summary of your next dose is shared with the app’s widgets on the same device so they can show it.
Apple Health
If you allow it, Dosenna reads your weight from Apple Health and writes the weight you log in the app to Apple Health. You can change this at any time in the Health app or iPhone Settings. Data from Apple Health is used only to show your weight in the app; it is never sent to me or to anyone else, never used for advertising, and never shared with Adapty.
Reminders
Dose and refill reminders are scheduled on your device as local notifications. They are not sent through any server.
AI features
For voice entry the app asks for access to the microphone and speech recognition. Your voice is turned into text on your device; the audio is not stored and is never sent anywhere. Voice and text entry, reading a medication label from a photo, and the doctor summary use Apple Intelligence on your device when it is available. On devices without it, or in languages it does not support, the text or photo you choose to process is sent over an encrypted connection to my server and to Anthropic’s Claude API to produce the result. Together with it the app sends the list of your medications and injection sites so the entry can be filled in. Nothing is stored on my server; the request is used only to return the result, and Anthropic does not use API data to train its models. These features run only when you use them.
Purchases and subscriptions
Dosenna Pro is sold through Apple’s App Store. Apple processes the payment; I never see your name, payment details or Apple Account.
The app uses Adapty (adapty.io), a subscription management service, to show the Dosenna Pro offer and to check whether your purchase is active. For this, Adapty receives:
- a random identifier created by the app on your device, not linked to your name, email or Apple Account;
- your purchase and subscription history for Dosenna;
- basic device and app information (such as device model, system version, app version, language and region) and your IP address;
- when the Dosenna Pro screen is shown.
Adapty never receives your medications, doses, weight or any other health data. Purchase data is used only to provide and restore purchases and to understand which offers work, not for advertising or tracking. See Adapty’s privacy policy.
Exports and reports
When you export a CSV file or create a PDF report for your doctor, the file is created on your device. It goes only where you choose to send or save it.
Anonymous usage statistics
To learn which features are used and where the app can be improved, Dosenna sends anonymous usage signals to TelemetryDeck (telemetrydeck.com), a privacy-focused analytics service based in the EU. A signal says, for example, that onboarding was completed or that a feature was used. It contains an anonymized identifier that cannot be traced back to you, the app version, the system version, device model and language. It never contains your name, email, the content you enter, photos or health or financial data, and it is not used for advertising or tracking across apps. See TelemetryDeck’s privacy policy.
What is not collected
Dosenna does not collect your name, email, contacts, location or photos, and has no advertising tools. The app does not ask to track you.
Your choices
- Delete individual entries in the app at any time.
- Deleting the app removes data on that device. To also remove synced data, delete Dosenna’s data in iPhone Settings → your name → iCloud → Manage Account Storage.
- Stop Apple Health access in the Health app → Sharing → Apps.
- To ask about purchase data held by Adapty, write to support@cassianvire.com and include the purchase date so I can find it.
Not medical advice
Dosenna is a personal log. It does not give medical advice, does not calculate or recommend doses, and is not a medical device. Always follow your healthcare provider’s instructions.
Children
The app is intended for adults and does not knowingly collect personal data from children.
Changes
If this policy changes, the new version will be published on this page with a new date.
