For DPOs
Are you a DPO? Everything is ready to frame the AI your teams already use.
Documents leave for AI assistants from every desk; you see none of them, and you are the one people will turn to. Take the diagnosis, then run the 90-day plan with a kit ready to adapt, to show your due diligence. Free, with no form and no address to leave.

Your organisation’s diagnosis
How well does DoNotLeak fit you?
A first inventory in ten questions, not a DPIA: a score out of 100 and the paths that fit you. Nothing is sent: everything is computed in your browser, and the link can be shared with your management.
Your result
Answered: 0 of 10
Answer a first question: your result builds here as you go.
20 / 100
Not a priority today
Said plainly: from your answers, DoNotLeak is not what you need first. The kit below stays free, and useful.
Where this score comes from
- Exposure0 / 50
- Suspected uses: 0 of 30 — a personal account counts 20, “I don’t know” 10, each other use 5.
- Sensitive data: 0 of 20 — 4 per category ticked (0).
- Coverage0 / 30
- No document language ticked yet.
- Deployability20 / 20
- The page, the API and the server image exist today.
Computed in your browser — none of your answers is sent or kept. The link carries your answers after the #, the part of an address a browser never sends to a server.

Measure
Volumes, never people
PowerPoint · FR, EN · The 90-day plan
Tools approved, people trained, incidents reported; DoNotLeak’s detections by type of data once it runs inside — never the content.
At any time
React
- The incident path, on the governance page
The incident path
PowerPoint · FR, EN · The templates to copy
Say it at once, contain, assess, notify the supervisory authority within 72 hours where feasible, unless the breach is unlikely to result in a risk to people: a report form, the elements of the notification and the letter to the people concerned, to adapt.
These documents are examples to adapt with your counsel: none of them is legal advice.
Your questions
What a DPO asks first — and where the proof is.
Each answer links to the page that proves it; what does not exist yet is said as such.
If something leaks, will they turn to me?
The controller is the organisation: it puts the measures in place and must be able to demonstrate compliance (GDPR, article 24). The CNIL, France’s authority, says so: the DPO is not personally responsible for the organisation’s non-compliance. Your role — inform, advise, monitor, raise awareness (article 39) — the kit makes visible, item by item.
Another tool nobody will use?
Ten seconds, no account, nothing to install: paste a text, see what would leave, keep what the AI needs. The reflex is learnt in the gesture itself: each detection is shown with its type, before sending.
Where does the data go?
The text you scan is processed in memory for the time of the scan, then forgotten: it is neither stored nor logged. The service calls no one — no AI provider, no third-party service. It is hosted by OVH, a French company, and published by Contee, in Paris.
Is it a surveillance tool?
No. The page asks for no account and sets no audience-measurement cookie; nobody reads what people write. The measurement the kit proposes counts volumes — tools approved, people trained, incidents reported — never people.
Is the detection perfect?
No, and the page says so: every detection lets something through. DoNotLeak shows everything it found, and the person reviews before sending. Replacing is pseudonymising, not anonymising: the protected text is still personal data under the GDPR.
Can it stay in the EU — or inside our walls?
The public page is hosted by OVH, a French host. For your teams, the same scan comes as a headless server image to run on your own servers, behind your identity provider: the texts never leave your information system.
And the works council?
The example charter is adapted with your staff representatives, where required. The kit holds a note for the works council, with four slides for the meeting, to inform them about the tool and the charter — to have reviewed by your counsel.
How do we meet article 4 of the AI Act?
Since 2 February 2025, an organisation that uses AI systems takes measures to develop its staff’s AI literacy; no certificate is required. The awareness webinar and the Seals’ training download today; the managers’ training, and the attestation that keeps its trace, are on their way.
