Privacy Policy for Erindra

Who we are

Erindra is published by Sandet Apps ApS (CVR 46701062, Denmark). Privacy questions: hello@erindra.app.

What Erindra stores — and where

• Your medication list, reminders and confirmations are on your device. We have no access to them, and they are not sent to us. If you use iCloud Backup or a Finder backup, the database containing them may be part of your backup (at Apple or on your computer).
• Photos: When you scan a box or a medication list, the image is read on your phone. Erindra never sends the image to any server — only the extracted text is sent for AI reading (see below). The image itself is stored locally on your phone as your own receipt, so you can always look up what you scanned. It is excluded from backups, and you can delete it at any time under Settings → Your scans. If you choose to share a photo, that happens through your iPhone's standard share sheet and is your choice.
• No account and no login. We know neither your name nor your email address unless you write to us. The app uses only the technical data it needs to work (see below).

About AI reading

To interpret the text on the label, the app sends only the extracted text (not the image) to our server, which forwards it to our AI provider (Anthropic) and returns the suggestion. Before sending, the app automatically removes personal ID numbers and tries to remove names. The text is used only to give you the result: we do not store it. Our server records a random device ID, timestamp and number of scans — used to track your free scans and to prevent abuse (see fair use below) — never the content.

Data processors: Supabase (server operation) and Anthropic (AI interpretation). Transfer to Anthropic (USA) takes place on the basis of the EU Standard Contractual Clauses (SCC).

Fair use of scanning

Your first 5 AI scans are free — one medication list counts as one photo. With Erindra Pro you get free scanning for normal use. To protect the service against abuse, a generous fair-use limit applies of up to about 40 scans per day and 250 per month; as you approach the daily limit you get a friendly notice. For fair-use purposes, our server counts only the number of scans tied to a random device ID — never what you scan.

Notifications and alarms

All reminders and alarms are scheduled and delivered on your device. Only the optional Lock Screen feature below, which you must enable yourself, uses a server.

Precise Lock Screen updates (optional, off by default)

Erindra can show a small card on your Lock Screen that you check off directly. If you enable "Precise Lock Screen updates" in Settings, the card can appear and change at the exact dose time — even when the app hasn't been running. To do this, the app shares your upcoming reminder times with our server (Supabase), which sends an update through Apple's push service. Only times, the name of the time slot (such as "Morning") and the number of doses are shared — never medication names, strengths or notes. The data is tied only to a random device ID, kept for at most 72 hours and deleted continuously. If you turn the feature off again, sharing stops and the stored times expire on their own. All reminders work fully without this feature.

Technical data and other recipients

Our server provider, Supabase, keeps ordinary operational logs that may include, among other things, your IP address and information about your device (user agent). They are used for operation and troubleshooting. Apple receives the codes and updates needed to deliver notifications and Lock Screen cards (push and Live Activities). The erindra.app website is hosted by Cloudflare, which can see visitors' IP addresses. If you write to us, your email may contain health information if you include it yourself; please do not send information you do not want to share.

Purchases

Purchases of Erindra Pro are handled by Apple. We never receive your payment details.

Your rights

You delete your medication list and your photos by deleting them in the app or deleting the app. Under the GDPR you have the right to access, rectification, erasure and to complain to your local data protection authority (in Denmark: Datatilsynet, datatilsynet.dk). Write to us if you have questions — real people answer.

Deleting scan photos

Photos are deleted individually or all at once under Settings → Your scans, and they disappear entirely if you delete the app. Because they exist only on your phone, we have no access to them and can neither provide nor delete them for you.

Changes

If we update this policy, we change the date at the top, and any significant changes are noted in the app's release notes.
