Privacy

No accounts

LearnGrok has no sign-up, no login for readers and no user profiles. You can read every page without identifying yourself.

What is stored

If you use the suggestion form, the fields you fill in are stored: the title, the link, your one-line description, the type you picked and, only if you choose to add it, a name. The form does not ask for an email address. Submissions are reviewed by a person and are not published automatically.

Sponsors

If you request a sponsor slot, we store what you put in that form: company name, the link, a copy of the icon from the site you gave us, and your email address. The icon is fetched once when the slot is approved and stored on our own file host, so that showing it never sends anyone who visits this site to yours. The email is used to talk to you about the slot and is never shown on the site. Payment itself is taken by Stripe; card details never reach this site, and we see only what Stripe shows us in their dashboard.

What the site counts about itself

The home page shows how many times the site has been visited and how many times somebody has opened or used a resource. Your browser asks the site to add one, and the site adds one. The same additions are kept three more ways, all of them counts and none of them a record of a visit:

• A total per day, so a week can be compared with the one before it.
• A total per page per day, which is how we see what people actually read. Your browser sends the path it opened. It is checked against the pages this site publishes and then added to that page’s total for the day, so a page that does not exist is never counted and no URL of yours is stored.
• A total per minute, kept for a few hours and then deleted, which is what makes the live view in the private admin area live.

None of them has a row per visit, an identifier, a cookie, a referrer or an order. Two pages read one after the other are two counts going up, and there is nothing in any of it that could put them back together into one person’s afternoon.

Nothing marks your browser for any of it, which is the other side of the same coin: one person reading ten pages is ten views, and the site has no way of telling that it was one person.

Your IP address

It is never stored. It is used to make a key: your address is hashed together with a secret that only the server has, and what the site works with is that hash. It cannot be turned back into an address, and an address cannot be looked up in it without already knowing both the address and the secret.

The key is what stops one caller hammering an endpoint. For the counters it stays in the memory of whichever server answered and goes when that process does. For the two features that call an AI provider, which are the ones that cost money, the hash and a count are written to a table so that every server agrees on the same limit, and the row is deleted once its window has passed. If your connection is IPv6 the address is cut to its network prefix before it is hashed, because that is the part your provider gave you rather than the part your device picked.

Analytics

The site uses Google Analytics to count visits and see which pages people read. It is loaded on every page and sets its own cookies; what it collects and how long it keeps it is governed by Google, not by us. We use it to decide what to write next, and we do not upload anything about you to it: no account, no email address, no identifier of our own.

Browser settings, an extension, or Global Privacy Control will stop it, and the site works exactly the same with it blocked. The two counters on the home page are separate and stay ours.

What is not stored

• No advertising or third-party marketing tags.
• No email addresses from readers; the site does not send email.
• No cross-site identifiers.

Local storage and cookies

Your light or dark theme preference is kept in your browser’s local storage. It never leaves your device and is not a cookie.

One cookie exists on the site: a session cookie set when an administrator signs in to the private admin area. Readers never receive it.

Hosting

The site is hosted on Vercel and its content is stored in a Neon Postgres database. Like any web host, those services process request data, including IP addresses, to serve and protect the site. That processing is theirs, governed by their own policies.

External links

Pages link to xAI’s sites and other third parties. Following a link takes you to a service with its own privacy practices, which this policy does not cover.

Changes

If this policy changes, the date at the top changes with it. The history of every change is public in the repository.
