Privacy
Draft, to be finalised before launch. Last updated 23 September 2026.
StrictDNS answers the address lookups your devices make, so it's in a position to see a lot. This page says plainly what we keep, who can see it, and when it's deleted.
What we store
Your account
You sign in with Apple or Google. We keep your name as your partners see it, your email address, and when you were last active. StrictDNS shares its accounts with our app ScrollBump, so the same account works in both.
Your devices
For each device you add: the name you give it, what kind of device it is, its private DNS address, and when it last used StrictDNS. That last time is how your partners are told when a device stops filtering.
What you block
Your chosen categories and apps, and the sites you've added to block or allow.
Your activity log, only if you turn it on
With the activity log on, we keep, for each device and day, which sites were looked up, whether they were blocked, roughly how often, and when. Not full addresses or page contents: only site names, likeexample.com. Entries are deleted after 30 days. With the log off, no sites are kept at all.
Partners
Who your partners are, the invitations you send, and the alerts sent to you.
Subscriptions
If you subscribe, Apple (or Google) handles the payment. We receive whether your subscription is active, through our payments provider RevenueCat, never your card details.
Who can see it
- You, always.
- Your partners see what you block, every change you make to it, your devices and whether each is filtering. They see your activity log only if you choose "Me and my partners". They never see your devices' DNS addresses.
- No one else. We don't sell your data, show ads, or share it for marketing.
Who runs it for us
- Cloudflare runs our DNS servers and stores devices, settings and activity.
- Google Firebase handles sign-in, partners and notifications.
- RevenueCat keeps track of subscriptions.
- Lookups for sites you don't block are passed on toCloudflare's public DNS to get their address.
Deleting things
Removing a device deletes its DNS address, so it stops working at once. Turning the activity log off stops new entries; old ones are deleted after 30 days. To delete your account and everything in it, emailprivacy@strictdns.com.
