Cookie & Local Storage Notice

Effective date: September 25, 2026 (Eastern Time, New York) · Last updated: September 25, 2026

1. The short version

This site sets no advertising cookies, no cross-site tracking cookies and no analytics cookies. It uses your browser's local storage — a small storage area on your own device — to make the app work and to remember your choices. Nothing in local storage is sent to us automatically.

2. What is stored

Name	Type	Purpose	Lifetime
kestrow-account	Local storage	Your account, goals, habits and log entries — the app itself	Until you delete the account or clear browser data
kestrow-session	Local storage	Keeps you signed in on this device	Until you sign out
kestrow-cookie-consent	Local storage	Remembers your choice on this notice	Until you clear it
kestrow-newsletter	Local storage	Only if you use the update-email form while emails are not connected: keeps the address you entered, on your device only	Until you clear it

The first three are strictly necessary: without them the app cannot keep your account or log. Our hosting provider may also set a strictly necessary security cookie to protect the site from abuse.

3. Optional storage

We do not currently use any optional cookies or analytics. If we ever add them, they will stay off unless you choose “Accept optional” on the notice, and this page will list them first.

4. Your choices

Change your choice at any time with the “Cookie settings” link in the footer of every page. You can also delete local storage through your browser's settings (usually under Privacy → Site data). Deleting it signs you out and erases the log stored on this device — export it first from Settings if you want to keep a copy.
