Privacy Policy

Last updated: April 22, 2026

Solum is built around a simple principle: your data belongs to you. This policy explains what we collect (very little), what we don't collect (almost everything), and how your data is handled.

Data we do not collect

• No personal information — no name, email, or identity of any kind is required to use Solum.
• No dose data — all vial configurations, administrations, schedules, and observations are stored exclusively on your device.
• No usage analytics — we do not track how you use the app, which screens you visit, or how often you open it.
• No crash reporting that transmits personal data — if we implement crash reporting in future, it will be aggregated and stripped of any identifying information before transmission.

Data stored on your device

Solum stores all data in a local SQLite database on your device. This includes:

• Vial templates and instances
• Administration logs
• Schedules and reminders
• Observations
• App settings

This data never leaves your device unless you explicitly export it using the in-app export function.

Subscriptions

Subscription purchases are processed by Apple via the App Store or by Google via Google Play. Solum does not handle payment information directly — at no point do we see your card, address, or Apple/Google account details. Receipts are validated through RevenueCat, which processes anonymized subscription events on our behalf. RevenueCat's own privacy policy applies to the data they handle.

Cloud Transfer

If you use the optional Cloud Transfer feature to move your data from one device to another, your data is end-to-end encrypted on your device before leaving it. Our server stores only an opaque encrypted blob it cannot read, and deletes it immediately after the new device downloads it (or after 24 hours if unclaimed). See our Cloud Transfer Privacy page for details.

Device backup

By default, your device may include the Solum database in a cloud or local backup (iCloud on iOS, Google backup on Android). This is covered by Apple's or Google's respective privacy practices. You can disable this in your device settings, or within Solum's Settings.

Your rights

Because we don't collect your data, there is nothing for us to delete, correct, or export on your behalf. All your data already lives locally on your device and is under your control.

To delete your Solum data entirely, uninstall the app from your device.

Children

Solum is not directed at children under 13 and we do not knowingly collect information from children.

Changes to this policy

If we make material changes to this policy, we will update the date at the top of this page and, where appropriate, notify you within the app.
