01Who is responsible

Lumen Tool is operated by Bit Blurry Studio, registered with the Dutch Chamber of Commerce under number 68341784. This notice applies to the website and Lumen Tool. For privacy questions or requests, contact franck@lumentool.com.

02Information and purposes

Lumen Tool processes connection and security information to operate and protect the website, your email address and subscription status to provide account access, and messages you send so we can answer them. Stripe handles billing and payment details on its own payment page. Card details never reach Lumen Tool. The live chat runs on tawk.to.

Creative work normally stays in your browser. Content is uploaded when you use Archive saving or upload features. The technical details, providers, processing locations, safeguards and retention periods are described in one place on the Data processing page.

Lumen Tool does not sell personal data, use it for advertising resale or use it to train AI models. Lumen Tool is not intended for children and does not knowingly collect personal information from children.

Data processing, providers and retention

03Necessary storage

Necessary cookies and browser storage keep you signed in, remember interface choices, local work and drafts, and save your analytics choice. These work independently of analytics. The analytics choice remains on this browser until you change it or clear browser storage.

04Website analytics

Lumen Tool uses Google Analytics 4 to understand website visits and improve the website. Analytics is enabled by default. Choose Disable analytics in the cookie notice or use the controls above to turn it off. Your choice is remembered in this browser, and disabling analytics does not affect access or payment.

Reports show traffic sources, landing pages, visited pages, returning visits, subscription choices, started checkouts and first paid subscriptions confirmed by Stripe. Renewals are not counted as new purchases, and duplicate payment notifications are not counted twice. A browser identifier connects visits and purchases on the same browser; it is not linked to your Lumen Tool account in Google Analytics.

No names, email addresses, payment details, Stripe customer identifiers, private projects or search text are sent to Google Analytics. Measured page addresses exclude query strings and fragments, apart from limited campaign labels used to identify traffic sources. Advertising features are disabled. We do not use session recordings, heatmaps, fingerprinting or personal profiling.

Analytics cookies last up to 60 days. Temporary checkout records expire after 14 days or are removed after the purchase event is handled. A non-identifying transaction key prevents duplicate purchases. Disabling analytics removes its cookies and tells the server to suppress pending conversions for that browser. Events already sent to Google cannot be recalled through this setting.

Google processes connection information to provide analytics. Cookie blocking, different devices and delayed payments can limit attribution. Service providers and processing locations are described on Data processing.

05Live chat

The chat button on the website runs on tawk.to, so you can ask Franck a question directly. The tawk.to chat loads with the website pages, also before you open it, so it can show whether Franck is online and keep an open conversation going across pages.

IP tracking is turned off in our tawk.to settings, so your IP address is not stored or shown. tawk.to does see the page you are on, your browser and device type and the country you visit from. It uses its own cookies and browser storage to keep an open chat going and recognize a returning visitor. Your name, email address and messages are stored only when you enter them in the chat.

Franck sees this information in the tawk.to dashboard to answer your question. It is not linked to your Lumen Tool account and is not used for advertising. Chats are kept until they are deleted; ask franck@lumentool.com to remove yours.

06Legal basis

Account access, subscriptions and requested storage are processed to perform our agreement with you. Necessary website operation, security, abuse prevention, the live chat and answering ordinary inquiries rely on legitimate interests. Legally required payment and accounting records are retained to meet legal obligations.

07Your rights

Depending on applicable law, you may request access, correction, deletion, restriction or a copy of your personal information, object to processing or withdraw consent. Send requests to franck@lumentool.com. You may lodge a complaint with the Dutch supervisory authority, the Autoriteit Persoonsgegevens.

08Changes

Updates to this notice are published here with the revision date. The controls above always show your current analytics setting.
