Privacy policy
Last updated: 4 August 2026
A coach that adapts to you has to remember you. That is the whole product, so there is no honest version of this page where we claim to hold nothing about you. Instead, here is exactly what we hold, who processes it, how long it stays, and how to get rid of it.
1 · Who is responsible
The controller for the processing described here is:
DataRBL AB
Company registration number 559385-4754
Agavägen 64, 5tr, 181 55 Lidingö, Sweden
privacy@claudemaster.ai
ClaudeMaster.ai is operated by DataRBL AB as part of the International AI Strategy & Architect Network.
2 · What we store
Your learning record. For every concept in the curriculum: whether you have shown you understand it, partly understand it, or have not got there yet.
What you have done. Your coach conversations, quiz answers, flashcard grades and how you rated your own study notes — the evidence the record is built from.
What you told us. Your goal in your own words, your working language, and your starting level from the intake conversation.
Your account. Email address and authentication data, so the record is yours and nobody else's.
Referral codes, if you invite someone, so we can tell where a new learner came from.
Technical logs — request timestamps, error classes and token counts — kept to keep the service working and to catch abuse.
3 · What we do not store
- Nothing about your code, your repositories, your files or your machine. We never read them.
- No advertising profile. We do not sell, rent or share your data with advertisers, and there are no advertising trackers on this site.
- No inference from time spent. Hours logged are not evidence of anything and we do not treat them as such.
4 · Why we are allowed to
Performance of a contract for your learning record, your account and everything the product needs in order to adapt to you. That is the service you signed up for; without the record there is no product.
Legitimate interest for the technical logs — keeping the service available, secure and free of abuse.
If we ever want your data for anything outside those two, we will ask you first, separately, and you can say no without losing access to anything.
5 · Who else processes it
To run the service we use a small number of carefully chosen processors, in these categories:
- Cloud and hosting providers, to run the application.
- Database and storage providers, to hold your account and your learning record.
- AI and language model providers, which generate your coach's replies. Your conversations pass through them.
- Email providers, for transactional messages such as sign-in links.
We never sell your personal data. If you want to know exactly which companies these are, ask us at privacy@claudemaster.ai and we will tell you — we keep a current register and we will not hide behind the categories if you actually want the names.
Some of these operate outside the EU/EEA. Where your data is transferred to a third country we rely on approved transfer mechanisms — the European Commission's Standard Contractual Clauses, or an adequacy decision such as the EU-US Data Privacy Framework. Primary storage is within the European Union.
6 · How long we keep it
We never keep your personal data longer than the purpose requires.
- Active account — as long as your account exists.
- Deleted account — when you ask us to delete your account, we remove it from active systems and confirm when it is done.
- Backups — security copies are rotated out on an ongoing basis.
- Technical logs — kept only as long as needed to operate and secure the service.
You can ask for deletion at any time and we will carry it out. We do not currently state fixed automatic retention periods, because we would rather describe what we actually do than publish a schedule and hope it matches.
7 · Your rights, and how to use them
You can ask us to:
- give you a copy of everything we hold about you (access),
- correct anything that is wrong (rectification),
- delete it, including your entire learning record (erasure),
- export it in a machine-readable format (portability),
- restrict or object to processing based on legitimate interest.
Email privacy@claudemaster.ai and we will answer within 30 days.
Deletion means deletion. The record goes, your progress goes with it, and we will tell you plainly that it cannot be restored rather than pretending otherwise.
If you think we have handled your data badly, you can complain to your national data protection authority. In Sweden that is Integritetsskyddsmyndigheten (IMY), imy.se.
8 · Changes to this policy
We date this page and note what changed. If a change is material — a new category of processor, a new purpose, a longer retention period — we will say so rather than quietly editing the page.
