Privacy policy

altr. needs no account and calculates in your browser. This page explains which data we process and why.

Draft text — awaiting lawyer review before launch. Not binding.

Controller

The controller's name and contact details will be added before launch.

No account, calculations in your browser

Picking a problem, setting a fix and seeing the result needs no sign-up. All calculations run on your device.

Private inputs such as weight are kept only in this tab's session storage (sessionStorage); they never go into links, share cards, our servers or analytics.

Text you type into the “What bugs you?” box is never sent or stored; matching happens in your browser.

Analytics (only with consent)

If you accept cookies, PostHog measures anonymous usage events: page type, chosen problem id, period changes, shares and app clicks. Free text, weight and e-mail are never part of these events. Without consent no event is sent.

Error logs

Sentry may be used to fix errors. Error logs contain no cookies, no user id and no free text from the URL.

Waitlist

If you join the app waitlist we store only your e-mail address, the problem id you chose, language and sign-up date, with your explicit consent. Data is kept on Supabase; hosting region and retention period will be added before launch.

Your rights

To exercise your rights under KVKK art. 11 and the GDPR (access, rectification, erasure, objection), write to destek@altrhabits.com. The formal request channel will be confirmed before launch.
