Privacy Policy

Effective date: 5 June 2026

This Privacy Policy explains how STEMR ("we," "us," or "our") collects, uses, and protects personal information when you use our collaborative audio feedback platform (the "Service").

Information we collect

  • Account data: email address, display name, username, profile picture if you add one, password (stored as a secure hash), and plan or billing status. If you use Sign in with Apple we receive an identifier from Apple and the email address you choose to share.
  • Project content: audio stems you upload or import from Dropbox or Google Drive, documents, project covers, waveform data, timestamped comments, replies, project titles, and collaborator invitations.
  • Usage data: log data such as IP address, browser type, device information, and timestamps of sign-in and core actions.
  • Device data: if you turn on notifications in the iOS app, a push token for your device.
  • Messages to us: feedback, bug reports, and reports about content or other users.
  • Payment data: if you subscribe to a paid plan, payment details are processed by our payment provider (e.g. Stripe). We do not store full card numbers on our servers.

How we use information

  • Provide, operate, and improve the Service.
  • Authenticate users and manage projects, invites, and notifications.
  • Process subscriptions and enforce plan limits.
  • Respond to support requests and protect against abuse or security incidents.
  • Comply with legal obligations.

How we share information

We do not sell your personal information, and we do not use it to track you across other companies' apps or websites. We share data with service providers that help us run the Service, only as needed to perform their work and under terms that protect it to the standard described here: Amazon Web Services (audio and file storage), Railway and Vercel (hosting), Resend (email), Stripe (payments), Apple (Sign in with Apple and push notifications), Dropbox (only if you connect your Dropbox account), and Google (only if you connect Google Drive). The people you add to a project can see its audio, comments, and your username. We may also disclose information if required by law or to protect the rights, safety, and integrity of STEMR, our users, or others.

If you connect Google Drive, we only access the files you choose, and only to copy them into your project.STEMR's use and transfer of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements. You can disconnect at any time from the Google Drive import window.

Data retention

We retain account and project data for as long as your account is active or as needed to provide the Service. You can delete your account at any time in Settings, under Delete account. That removes your account, your sessions, and every project only you belong to, including its audio, and cancels any paid plan. Projects you share with other people stay with them, and your comments there stay without your name on them. We may keep limited records where the law requires it.

Security

We use reasonable technical and organizational measures to protect personal information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Cookies

We use cookies and similar technologies to run the Service, remember your preferences, and keep you signed in. We do not use analytics or advertising cookies unless you accept them in our cookie banner. For a full list of cookies, how long they last, and how to manage them, see our Cookie Policy.

Your rights

Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal information. Contact us at contact@stemr.co.uk to make a request. See also our Data Compliance page.

Children

The Service is not directed to children under 16, and we do not knowingly collect personal information from them.

Changes

We may update this Privacy Policy from time to time. We will post the revised version on this page and update the effective date above.
