What stays in your browser

These never leave your device. You can clear them in your browser settings at any time.

What reaches the server when you read

The site runs on Cloudflare. Every request to it passes through Cloudflare's network, so Cloudflare processes your IP address and the usual request headers to deliver the page.

• Interface language. If you haven't set the ui cookie, the site picks the language from the country Cloudflare detects for your connection and from your browser's language setting. It uses this to choose English or Ukrainian and doesn't store it.
• Technical logs. For the first month after launch, Cloudflare keeps a log of requests to the site for up to 7 days, so I can find out why something broke. A log entry includes the address you opened, the time, technical details of the request and may include your IP address. For searches, the address contains what you searched for. After that month request logs are turned off.
• Visitor statistics. I use Cloudflare Web Analytics to count page views. It uses no cookies and no local storage, and doesn't fingerprint visitors by IP address or browser (Cloudflare's description).

Search

When you search inside a book, your query goes to the site's search service.

• Before your first search, your browser passes a quick automated check, Cloudflare Turnstile, which keeps bots away. For this check Cloudflare processes your IP address and technical signals from your browser. You get a search pass that lasts 30 minutes.
• To find passages by meaning and not only by exact words, your query is processed by Cloudflare Workers AI. Logging is turned off for these requests.
• The answer to a query is cached for one day, so the same search is faster next time. The cache keeps only the query text and the result, nothing about who searched.
• To stop abuse, the number of searches per IP address is limited for a few seconds at a time. The counter isn't saved.

Error reports

When you report an error, I receive: the book, chapter, page and paragraph; the link to that place; what you wrote (the text you selected, what it should be, your comment, the labels you ticked); the interface language; the time on your device and on the server; and the country Cloudflare detected for your connection.

Your IP address is used only to limit how many reports can be sent per minute. It isn't saved with the report.

I read every report myself. I keep reports on the server for 90 days after I've collected them for reading; my working copy stays in my notes so I know what was fixed. Please don't put personal information in the comment: it isn't needed.

Book suggestions and notifications

• A suggestion (title, author, link) is public once I've approved it. Your name isn't asked for and isn't shown. Links are visible only to me unless they point to a few well-known libraries of scanned books.
• A vote is stored with a random identifier that your browser creates for this site, so one browser counts once. To stop vote stuffing I also store a scrambled code derived from your network address that changes every day and can't be turned back into the address. I delete that code after 30 days.
• Email for "tell me when it's ready": I send one email to confirm, and nothing happens until you press the button on the confirmation page. If you don't, the address is deleted after 7 days. When the book is published, or if it turns out I can't add it, I send one email about that, and the subscription to that book is deleted. An address with no subscriptions left is deleted within a day. Every email has an unsubscribe link that works with one click. I never use the address for anything else, and there's no newsletter. If a subscription is still waiting after 3 years, I ask once whether you still want it and delete the address if you don't answer. If you unsubscribe with the button, the address is deleted completely. If an email to the address bounces, I keep only the address marked as blocked, so that the site never writes to it again. Emails are sent through Cloudflare Email Service. They contain no tracking pixels and no rewritten links.

Who else handles the data

Cloudflare, Inc. hosts the site and provides the logs, statistics, bot check, AI search and email sending described above. Their servers are in many countries, including the United States. Their policy: cloudflare.com/privacypolicy.

No one else gets data from this site. I don't sell it, and I don't use it for advertising or profiling.

Your rights

You can ask me what I have about you, ask me to correct it or delete it, and object to how I use it. Write to the address above. I don't store names or accounts, so tell me what to look for: your email address, or the date and text of your report. I'll answer within a month.

If you're in the EU, the EEA or the UK, you can also complain to your data protection authority.

The legal basis, in GDPR terms: emails are sent only with your consent, which you can withdraw by unsubscribing. Limits, logs and the bot check rely on legitimate interest in keeping the site working and free of abuse. Everything else is needed to do what you asked for.
