Privacy Policy

Bookplate keeps a copy of what you read. It is built so that the library it makes does not leave your Mac by itself: there is no account, no sync, no analytics and no advertising.

This policy is published by Guo Taihang, an individual developer in China, who makes and sells Bookplate and is responsible for the personal information described below.

What is kept on this Mac

Bookplate stores everything it knows in its own container on your Mac:

• the links you save, and the copy the app makes of each page — the article’s text and its images;
• the tags, notes and reading position you give an item, and whether you have read, starred or archived it;
• the search index, built from the text of everything you have saved;
• the item titles macOS Spotlight indexes, so a saved article is a keystroke away;
• anything you export, in the folder you chose for it.

Nothing in that list is uploaded anywhere. A link you share to Bookplate from another app reaches it through the app group the app and its Share extension share on your Mac, and goes no further than the library. Deleting an item in the app deletes its copy with it.

What leaves this Mac

Bookplate makes two kinds of request, and both are ones you asked for by saving a link.

• The pages you save. Bookplate fetches the address you saved, and the images in it, from the site that serves them. That site sees the request, as it would if you had opened the link in your browser. We do not: the request goes from your Mac to that site, not through anything of ours.
• The Internet Archive. When a live page cannot be read, or yields no article, Bookplate asks the Internet Archive’s Wayback Machine for a capture of that address and makes the copy from it. The Internet Archive sees the request for the capture, and nothing else.

Reading makes no request at all: the reader blocks every load that is not from your own library, so a stored page cannot fetch anything while you read it. That is also why nothing can track you from one of them.

What we hold about you

Nothing about your reading. Bookplate contains no analytics, no crash-reporting SDK, no advertising and no account, so nothing about what you do in the app is reported to us, and your library exists only on your Mac. There is no server of ours for it to reach.

Buying the unlock is between you and Apple. Apple takes the payment, issues the receipt and keeps the record of the sale; we are not given your name, your email address or your payment details, and we receive no report of who has bought Bookplate. What Apple does with the purchase, and with the Apple ID it is tied to, is covered by Apple’s own privacy policy. Whether the trial or the unlock is active is told to the app by Apple, on your Mac. Refunds are Apple’s to give, and asking for one is between you and Apple.

Your controls

• Export… writes everything Bookplate holds into a folder you choose, as files that do not need Bookplate to open: each article as HTML and as Markdown, the images, a JSON manifest and a bookmarks file. It works during the trial, after it, and with no purchase at all.
• Delete… removes the selected item and the copy Bookplate made of it from this Mac.
• There is no account to close and nothing to ask us to delete, because nothing about you reaches us in the first place.
