Privacy statement

Last updated 1 October 2026. This statement covers the Kaydence app for Windows, version 1.0 and later, and this website.

The short version

Your diary never leaves your PC.
There are no accounts, no adverts, no analytics and no tracking.
Kaydence collects nothing about you. The developer never sees your diary or anything about how you use it.
The only thing the app sends over the internet is an optional check for a new version.

Who makes Kaydence

Kaydence is made by KaydeeCodes, an independent developer (kaydee.codes). Because Kaydence doesn't collect any personal information, KaydeeCodes doesn't hold any information about you as a Kaydence user.

Your diary stays on your PC

Everything you put into Kaydence is stored in a folder on your own computer, %LocalAppData%\Kaydence. That includes:

your writing, check-ins, moods and anything else you fill in
photos, drawings and voice notes
your settings, backups and logs

None of it is uploaded, synced or shared. There's no Kaydence server and no cloud account. Backups go only to the folder you choose, such as a folder on your PC or a USB stick.

If you choose to keep your diary or backups in a folder that another service syncs, such as OneDrive, that service's own privacy terms apply to those files. Kaydence doesn't do this by default.

Encryption

You can set an optional password. When it's on, every file in your diary is encrypted with AES-256, so anyone who copies your files sees only scrambled data. Your password is never stored, only a scrambled hash used to check it. The recovery file Kaydence asks you to save is a spare key that only you hold. There's no back door, which also means nobody, including the developer, can recover an encrypted diary if both the password and the recovery file are lost.

Photos

Photos taken on phones and cameras often contain hidden details, such as the exact place a photo was taken, the date and the camera model. When you add a photo, Kaydence saves a clean copy without those details. Your original file is never changed.

What the app sends over the internet

The update check (optional) Once a day, Kaydence asks GitHub, where Kaydence is published, for the number of the latest version, using GitHub's public address api.github.com. The request includes the Kaydence version number, so GitHub can serve it correctly. Nothing about you or your diary is sent. Like any website, GitHub can see the request came from your internet connection's IP address, as described in GitHub's privacy statement. You can switch the update check off in Settings, Help and feedback, and check by hand whenever you like.

That's the only connection Kaydence makes by itself. It has no analytics, crash reporting service, adverts or tracking of any kind.

Links you choose to open

Some buttons in Kaydence, like Report a problem, Suggest a feature, the guide's links and the website link, open a page in your own web browser. Report a problem fills in your Kaydence and Windows version numbers to help find the issue. Nothing from your diary is ever added. What you then do on those websites is covered by their own privacy terms, such as GitHub's.

Logs and bug reports

Kaydence keeps a log on your PC of what the app does, such as which screen opened, how long a save took and any errors. It's kept for 14 days and never leaves your PC unless you choose to share it.

Logs never contain anything you wrote, your check-in answers, passwords, keys, search words or anything you copied.
Your Windows user name is hidden in any file path.
Make a bug report saves a zip of recent logs and a list of your settings, with passwords, keys and hashes shown only as "set" or "none". It's saved on your PC. You decide whether to attach it to a problem report, and you can open it and read every file first.

Exports and printouts

When you export your diary or save it as a PDF, the files are written where you choose and are not encrypted. They stay entirely under your control.

Children

Kaydence doesn't collect information from anyone, of any age.

This website

This website doesn't use cookies, analytics or tracking scripts, and it doesn't ask for any information. Like all websites, the company hosting it may keep standard technical logs, such as IP addresses and the pages requested, for security and to keep the site running. Download links go to GitHub, where GitHub's privacy statement applies.

Health information

Kaydence's optional health, period and transition tools store your notes on your PC like everything else, and they're never sent anywhere. Kaydence is a diary, not a medical app, and nothing in it is medical advice.

Changes to this statement

If Kaydence ever changes how it handles your information, this page will be updated before that version is released, with a new date at the top. Any change will be mentioned in the release notes.

Questions

If you have a question about privacy in Kaydence, please open an issue on GitHub, or for anything sensitive, use private reporting.
