| Category | What it includes | Where it comes from |
|---|---|---|

We only use your data for the purposes below. Under the EU and UK GDPR, each purpose needs a legal basis.

4. Who we share data with
We share personal data only with service providers that help us run birger.ai. Our contracts require them to protect it and to use it only on our instructions.

We may also disclose data if the law requires it, to protect our rights or users’ safety, or as part of a merger or sale of our business, in which case we will tell you first. We never sell your personal data.
5. Where your data is processed
Some of our providers process data in the United States: Google Analytics (Google Ireland Limited may transfer data to Google LLC), Cloudflare and Resend.
Where data is transferred outside the EEA or UK, we rely on appropriate safeguards: the EU–US Data Privacy Framework (where the provider is certified), the European Commission’s Standard Contractual Clauses, or the UK International Data Transfer Addendum. You can ask us for a copy of the relevant safeguards.
6. How long we keep your data
| Data | How long we keep it |
|---|---|
| Waitlist email | Until you unsubscribe, or 12 months after launch |
| Google Analytics data | 14 months |
| Direct communications | Up to 2 years after the conversation ends |
7. How we protect your data
- All data is encrypted in transit (HTTPS) and at rest.
- We protect the site and the waitlist against automated abuse.
- Only staff who need access to run or support the site can access personal data.
No system is perfectly secure. If a breach affects your personal data, we will notify you, and the relevant authority where the law requires it.
8. Your rights
Under the GDPR you have the right to:
- Access the personal data we hold about you and get a copy
- Correct inaccurate data
- Delete your data (the “right to be forgotten”)
- Restrict or object to our use of your data, including use based on legitimate interests
- Data portability: receive your data in a commonly used, machine-readable format
- Withdraw consent at any time, where we rely on consent: for analytics with Cookie settings (section 9), for the waitlist with the unsubscribe link in any email
To use any of these rights, email contact@birger.ai. We will reply within one month. You also have the right to complain to a data protection authority, such as the one where you live or work, or ours: the UK ICO (ico.org.uk).
10. Third-party links
birger.ai may link to websites we do not own or control, such as GitHub and Hugging Face, where we publish code and models. This notice does not cover them, and we are not responsible for how they handle your data. Please read their privacy policies before giving them any information.
11. Changes to this notice
We may update this notice, for example when Reflexr launches. If we make significant changes, we will tell you by email before they take effect. The “last updated” date at the top shows the current version.
