What is collected, where it is kept, who can see it
This site is built to collect as little as possible. The free check runs in your browser and does not send your answers anywhere.
The free check
Your answers are held in the page while you use it and are not transmitted to us. Clearing the page or closing the tab removes them. There is no account, no cookie for the check and no analytics call from the check.
Where it is kept and who can see it
The site is served by Cloudflare Pages. Payments are processed by Stripe. Transactional email, if you start the watch, is sent through SendGrid. Server logs are held by Cloudflare for a short period for security and abuse prevention. We do not sell, rent or share personal data. We do not run advertising trackers.
If you buy the kit or the watch
Stripe processes the payment and sends us the email address and the subscription status. We use the email to deliver the download link and, for the watch, to send the change email. You can cancel the watch from the Stripe receipt. You can ask us to delete your email from the watch list at any time by writing to support@theartofservice.com.
Your rights
You can ask what we hold about you, ask for a copy, ask for a correction or ask for deletion. Write to support@theartofservice.com. We answer within 30 days. If you are in the European Union or the United Kingdom, you also have the right to complain to your data protection authority.
Cookies
