The essential information on how the service works, your rights and your responsibilities.

This page is an English translation of the French text, provided for convenience. In case of any difference, the French version prevails.
In short
What you enter in the tool does not leave your browser. There is no account, no password and no server receiving your work. OLHYN has no copy of the website you are building and no way of accessing it.
This is not just a statement: your website in progress is sent to no server, and no cookie is placed on your device. You can check this in the Network tab of your browser's developer tools.
One exception, which we prefer to state openly: anonymous audience measurement counts the pages viewed, to know whether the tool is used. It sets no cookie, follows nobody from one site to another and sees nothing of what you enter. The details are in section 2.
1. What is stored, and where
Your website in progress is stored in your browser's local storage, an area specific to your device (known aslocalStorage). This covers what you enter: your business name, town, text, the contact details shown on your future website, colour and layout choices.
This storage has a strictly functional purpose: letting you pick up your work where you left it. As such, it does not require your prior consent, being necessary to provide the service you have expressly requested. No other tracker is used.
For how long
With no time limit set by OLHYN, since this data is not in its hands. It stays on your device until you delete it.
How to delete it
- The "Reset to the template" button in the editor replaces your work with the blank template.
- Clearing your browser data for this website deletes everything.
Be careful, this also works the other way: clearing your browser, changing device or using a private window makes your work disappear, and OLHYN cannot restore it. The Settings panel lets you download a JSON backup you can import again before changing device. Once your website is online, its content is backed up in your own GitHub repository from Storyblok.
2. What OLHYN actually processes
Audience measurement. We use Cloudflare Web Analytics, which counts the pages viewed without setting a cookie, without a unique identifier and without following visitors from one site to another. None of the content you enter in the tool is sent to it. This processing is based on our legitimate interest in knowing whether the service is used and which pages cause problems. As nothing is written to your device, it does not require your prior consent under article 82 of the French Data Protection Act (loi Informatique et Libertés).
The hosting provider's technical logs. Like any website, this one is served by a hosting provider, Cloudflare, which records technical logs including your IP address. This processing is based on the legitimate interest of keeping the service secure and working properly. These logs are kept by the hosting provider for its own periods, set out in its privacy policy.
Your website itself is prepared and downloaded entirely in your browser, as a single file: OLHYN collects no email address to send it to you, and knows neither its content nor its download.
3. Your rights
You have the right to access, rectify, erase, restrict and object to the processing of the data mentioned in section 2. You can exercise these rights through the oktanagency.com contact page.
The data in section 1 is outside this scope for a simple reason: OLHYN does not hold it. You have direct and complete control over it from your browser.
If, after contacting us, you consider that your rights are not respected, you can lodge a complaint with the French data protection authority, the CNIL (cnil.fr), or with the supervisory authority of the EU Member State where you live or work (Article 77 GDPR).
4. The website you publish
Once your website is online, it is hosted on the accounts you have opened in your own name, with the providers of your choice. OLHYN has no access to it and plays no part in processing your own visitors' data. The information and compliance obligations attached to that website are yours, as its publisher.
