Jam-da is made by Väder AB (“we,” “us”), a Swedish company. The app is local-first: almost all of your data stays on your own phone. There is no account, and we do not collect your name or email address.
Most of what you do in Jam-da — your library of tunes, your audio recordings, playlists, personal notes and settings — is stored locally in a database on your phone. We have no copy of it and cannot read it. The built-in tune catalog ships with the app and is read-only; it contains no information about you.
The microphone is used only while you are recording a tune. Your recordings are saved on your device; they are never included in our analytics or crash reports, and they leave your phone only if you turn on backup (encrypted — see below) or choose to share them. The camera is used only to scan a friend’s QR code — no photos are taken or stored.
Backup is optional and off by default. If you turn it on, a copy of your library is uploaded to our cloud (Cloudflare R2). The copy is end-to-end encrypted with a key only you hold — derived from your 12-word recovery phrase (the same phrase as your jam identity). This means we store your data but cannot read it: without your phrase it can’t be opened, and we cannot hand readable content to anyone.
Keep your phrase safe. If you lose it, neither you nor we can restore the backup — that is the price of no one else being able to reach it.
When you explicitly choose to share a tune, a set or a library — or join a shared jam — that specific content is sent via a temporary relay (Cloudflare). Only what you choose to publish leaves your device, it is identified by anonymous codes with no link to you, and it is deleted automatically after about seven days. If you don’t use the sharing features, nothing is sent.
To understand what gets used and improve the app, we may collect anonymous statistics via PostHog (servers in the EU). These are events such as which screens are opened and that a tune was played — tied to a random device ID, never your name or email. The content of your recordings and notes is never included. You can turn this off at any time under Settings → Privacy.
To find and fix bugs, the app may send anonymous crash reports via Sentry (technical information such as device model, OS version and app version). Nothing is sent during development, and the reports contain no personal profile.
Jam-da is free. If you choose to support development with a voluntary donation, payment is handled entirely by the App Store or Google Play. We never see your card details — only that a purchase was made.
A tune’s detail page may include links to Spotify and YouTube. When you follow such a link you leave Jam-da and are covered by that service’s own privacy policy. We share no data with them when you open a link.
As a Swedish company we comply with the GDPR. To the extent we process any personal data, we do so to provide the app’s features (contract) and for our legitimate interest in improving and securing the app. Anonymous statistics rely on your consent, which you can withdraw in the app.
Some providers (such as Sentry) may process data outside the EU/EEA. Where that happens we ensure appropriate safeguards, such as the EU Standard Contractual Clauses.
You have the right to request access to, correction of, or deletion of personal data, and to object to certain processing. Because most of your data is local, you can delete it yourself directly in the app, or by uninstalling it. For anything else, contact us at hello@jamda.app.
You also have the right to lodge a complaint with your data protection authority. In Sweden this is the Swedish Authority for Privacy Protection (IMY), imy.se.
You can delete your data at any time:
Because there is no account and no readable personal data on our side, there is no account to delete. Any questions about your data? Contact hello@jamda.app.
Jam-da is intended for a general audience and does not knowingly collect data about children.
We may update this policy. Material changes will be announced in the app or by updating the date above.
