Privacy policy

Last updated: 11 November 2026

This policy tells what personal data Nuanze keeps, why, who else gets it, and what your rights are under the GDPR. For any question about your data, write to [email protected].

What we keep

• Account: you sign in with Google. We get your name, email address and profile picture from Google. We do not get or keep a password.
• Your texts: the sentences and articles you paste, and their analyses, in your history. Also your Later marks and the knots you mark as Known.
• Usage: for each task, the number of words, the model and the cost, to apply the limits of your plan.
• Payments: your plan, its status and your Stripe customer number. Stripe keeps your card details; we never see them.
• Technical data: server logs with your user number and errors, to find faults and abuse.

Why, and on what legal basis

• To give you the service you signed up for: account, analyses, history, limits and payments (contract, art. 6(1)(b) GDPR).
• To keep the service safe and working: logs and abuse checks (legitimate interest, art. 6(1)(f) GDPR).
• To keep payment records for seven years, as Dutch tax law requires (legal obligation, art. 6(1)(c) GDPR).

We do not sell your data. We do not use it for advertising. We do not use your texts to train models.

Where your data is, and who else gets it

The app and its database run on a virtual private server that we rent and manage ourselves. Only these companies receive data from us:

• OpenAI analyses the texts you send. We ask OpenAI not to store them; OpenAI can keep API data for a short time to detect abuse, as its API policy says.
• Stripe handles payments, invoices and taxes.
• Google signs you in.

These companies are in the United States. Transfers of data to them use the EU–US Data Privacy Framework or the EU standard contractual clauses.

Cookies

Nuanze uses one cookie to keep you signed in. It is needed for the service, so it needs no consent. Some settings, such as the language you say things in, stay in your browser only. There are no analytics or advertising cookies.

How long we keep data

• Your account, history and marks: until you delete them or your account.
• Usage counts: 24 months.
• Server logs: 30 days.
• Payment records: seven years.

Your rights

You can ask to see, correct, export or delete your data, and you can object to its use. Write to [email protected] from the email address of your account; we answer within one month. You can also complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.

Changes

If this policy changes in a way that matters, we tell you by email before the change starts.
