Privacy policy
Effective November 10, 2026
The short version: Blokvane does its blocking inside your browser. Your browsing history, searches and the pages you visit are never sent to Blokvane or anyone else. Blokvane only stores what it needs to run your free trial and your Pro plan, and it never sells or shares data for advertising.
1. What stays on your computer
These are kept only in your browser's own storage and never sent to Blokvane:
- Your settings, paused and blocked sites, hidden elements, time limits and supported creators.
- Dashboard counts: how many ads and trackers were blocked, time saved and similar numbers.
- The "What advertisers think you are" profile, built from clues inside ads Blokvane blocked.
- How long you spent today on sites with a daily time limit.
- Country blocking: the countries you block, the sites and server addresses you trust, the counts per country, and the sites that were found in a blocked country. Which country a server is in is worked out on your computer from a table inside Blokvane.
- Copies of the lists Blokvane downloads.
- Friends: your friends' names, your chats with friends and groups, the groups you're in, Work together's timer, to-do list and notes, and your Friends settings. These are kept only on your computer and on your friends' computers. They go from computer to computer sealed, so only you and your friends can read them. Voice calls and Help on a page go straight from one computer to the other. Blokvane never sees any of it.
- Blokvane Games on your phone: your sign-in to host party games, kept only on that phone.
- Live polls on your TV screens: each screen that shows a poll keeps its votes (for each phone, a random key made just for that poll, and the answer it picked), and each phone keeps its own vote. No names, and nothing else about the phone.
If you turn on "Sync across computers", your hidden elements, paused sites and blocked sites are saved in your browser's own sync (Google for Chrome, Microsoft for Edge) so they show up on your other computers. That goes through Google or Microsoft, not through Blokvane.
2. What Blokvane's server stores
| What | Why |
|---|---|
| A random id for each browser where Blokvane is installed, the browser name (Chrome or Edge) and a computer name like "Chrome on Windows", and when it was last used | To know which computers use your Pro devices and your free trial |
| A scrambled (keyed hash) form of the email of the Google or Microsoft account your browser is signed in to, or of the email you typed for the trial | So each person gets one free trial. The scrambled form can't be turned back into your email |
| Your email address, when you sign in, buy Pro or are given Pro by someone | To sign you in, send sign-in links, sign-in codes and invites, and link your devices to your plan |
| Your plan: monthly or yearly, number of devices, renewal date and payment status | To turn Pro on for the right devices |
| Who you gave a device to, and on which browser | So the people you invite can use Pro |
| A scrambled form of your internet address (IP address) when you ask for a sign-in link or code, start a trial or send an ad report | To stop abuse, like someone sending thousands of emails or trials |
| Ad reports you choose to send: the screenshot you approved, the page address, your note, the Blokvane version and browser, and a scrambled id of this copy of Blokvane (to stop abuse) | To fix ads that got through, for everyone |
Card numbers and other payment details go straight to Stripe. Blokvane never sees or stores them.
3. Services Blokvane uses
| Service | What for | What it receives |
|---|---|---|
| Render (United States) | Runs Blokvane's server and database | The data in section 2 |
| Stripe | Payments, invoices and receipts | Your email, your plan and your payment details |
| Resend | Sends sign-in links, sign-in codes and invites | The email address and the message |
| GitHub | Keeps a text copy of ad reports in a private place only Blokvane can see (the screenshot stays on Blokvane's own server); hosts Blokvane's public lists and daily fix file | The page address, note, Blokvane version and browser of reports you send; a normal download request for lists |
| GitHub, jsDelivr, Have I Been Pwned | The filter, security, AI-site and breach lists, the daily fix file, and a fresh country table about once a week while Country blocking is on | A normal download request. Nothing about you |
| rdap.org | Lookalike warning (Pro): how old a login page's domain is | That domain name |
| Free public relays (Nostr and MQTT servers run by others) | Connect: let your phone, your computers, your friends and your TVs find each other, and carry their sealed messages | Sealed messages they can't read, and the time they were sent |
| The website an image or short link came from | Before AI image check and short link preview | A second request for that image or link |
Each of these can see your internet address, like any website. The list and lookup services can be turned off in Blokvane's Settings, under Privacy.
4. What Blokvane never does
- It never collects your browsing history, searches, passwords, emails or the content of your pages.
- It has no analytics, no advertising and no tracking of its own, in the extension or on blokvane.com.
- It never sells, rents or shares your data for advertising.
5. How long data is kept
Sign-in links and codes stop working after 15 minutes and are deleted after 30 days. The scrambled trial records are kept, so the same person can't start a second trial. A record of account changes, like a device added or removed, is kept for one year. Signed-in sessions end after 180 days without use. Device records are kept while you have Pro, and a computer not used for 45 days is removed from its device slot. Ad report screenshots are deleted after 14 days; the rest of a report is kept for up to one year. Billing records are kept as long as the law requires. When you delete your account, everything else about you is deleted.
6. Your choices and rights
You can see your devices and plan, and delete your account, on blokvane.com/account. To get a copy of your data or ask anything about it, email support@blokvane.com. Wherever you live, Blokvane gives you the same rights to see, correct and delete your data.
7. Children
Blokvane accounts are for people 13 and older, and only adults can buy Pro. Kid mode works on the computer and sends nothing about the child to Blokvane. Please don't give Pro to a child's own email: sign in on their computer with your email instead.
8. Permissions the extension asks for
Blocking ads and scams means looking at every page you open, so Blokvane asks your browser for broad permissions. It uses them only on your computer, to block, hide and warn. It also asks to know your browser account's email, only to keep one free trial per person, and it sends that email only in scrambled form.
9. Changes
If this policy changes, the new version will be posted here and in the extension, with a new date at the top. Big changes will be explained before they apply.
