Privacy policy.
Data you share with me or my apps is used only for the purpose you shared it for. It is never sold, never shared with third parties for their own use, and never used for advertising.
Who
Johan van der Boog, Utrecht, the Netherlands, is the controller for this website and for the apps and integrations I operate (“my apps”). Contact: [email protected].
What and why
My apps access only the data you explicitly authorise, for example calendar events through a sign-in with Google, and only to provide the feature you authorised it for. The legal basis is your consent (GDPR art. 6(1)(a)), which you can withdraw at any time.
Sharing
I do not sell, rent or transfer your data to anyone, and no third party may use it for its own purposes. Data is shared only with providers that host or transport it on my behalf, under data processing terms, or where the law requires it.
Google user data
Use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. It is not used for advertising, not read by humans unless you ask or the law requires it, and not used to train AI models.
Storage and retention
Data is stored on infrastructure I control in the EU, protected by encryption in transit and access controls. It is kept only as long as the feature needs it and deleted when you revoke access or ask me to.
This website
No cookies, analytics or trackers. Your colour theme is stored only in your own browser. Requests pass through Cloudflare, which processes technical data such as IP addresses to deliver and protect the site; server logs are kept briefly for security.
Your rights
You may request access to, correction, deletion, restriction or portability of your data, object to its processing, or withdraw consent; email me. You can revoke Google access at myaccount.google.com/connections. You may also complain to the Autoriteit Persoonsgegevens.
