2.2 Your Writing Log

When you write in BYOK Studio (on the web, on your computer or on your phone) or on a BYOK device, we keep a private writing log for each of your projects. It shows you how your writing came together. If you choose, it can also show readers how a piece was written, with a BYOK Seal (below).

For each day and each file, the log notes:

• how many words you typed, pasted, dictated or added with another tool, imported, moved between files or brought in from a BYOK device, and how many you deleted
• how many keys you pressed, how often you corrected with Backspace or Delete, how often you moved the cursor before typing, and how long you paused between key presses, counted in eight ranges from under a tenth of a second to half a minute (never which keys)
• how often you pasted and the size of your biggest paste
• how you edited: how many words you revised inside existing text, and how often you fixed spelling, rearranged paragraphs, sections, outline rows, cards or tiles, and used find and replace
• when you wrote, in five-minute blocks, about how long you spent in each file, how often your work was saved and which kind of app you used
• for a BYOK device, which device it was and when it synced
• how many words a file had when its log began and at the end of each day

To check the log, our server also notes, for each file and day, when your saves arrived (in five-minute blocks), the fastest pace at which words arrived, how many words arrived faster than anyone can type, and how many were saved while you were offline. It also keeps your time zone, so the log’s days match your calendar. Each day, it seals your log with a fingerprint of these numbers, so it can later show that the log hasn’t been changed.

Numbers and times only. The log never holds your words, your file names or which keys you pressed. The only name it keeps is the title of a BYOK Seal you make: the name of what you sealed. It’s tied to your account so that Studio can show it to you, but nothing in it can be used to read or rebuild what you wrote.

Where it’s kept. With your account, if you have one. The desktop app also keeps a copy on your computer, which is included when you use Back up library. In local mode, without an account, the log stays on your computer and joins your account only if you later turn on sync. In a web browser, the newest counts wait in the browser until they are sent to your account.

Who can see it. Only you, in Studio, unless you make a BYOK Seal. We don’t show it to anyone else, sell it or use it for advertising.

BYOK Seals. When you choose “Add a BYOK Seal” on an export, or make a Seal link, we make a public record of how that piece was written. Anyone with its code or link can see it. A Seal shows its title (the name of the file or manuscript you sealed), the counts from your log for the files it covers (days, time and how the words arrived) and when it was made. It also holds a fingerprint of the text as exported, scrambled with a random key, so a reader can check that their copy matches; the fingerprint can’t be turned back into your words. A Seal never shows your text, the names of other files or your other projects. You can withdraw a Seal at any time in Studio; it then shows only that it was withdrawn and when. Erasing a project’s log, or your whole log, withdraws the Seals made from it, and deleting your account deletes all of them.

Erasing it. You can erase one project’s log, or your whole log, at any time in Studio. Recording carries on from then. When you erase, we keep only your time zone and a record of which uploads we have already counted, so nothing is counted twice. Deleting a project deletes its log, and deleting your account deletes all of it.
