Privacy Policy
Last updated: 16 July 2026
Who we are
2xKit (“we”, “us”) is operated by CloudBrain, based in India. Contact us about privacy at contact@2xkit.com.
What we collect
- Account data: email address, and if you sign up with a password, an encrypted password hash (we never see or store your plaintext password, authentication is handled by our database provider, Supabase).
- Content you choose to save: calculation inputs and results you explicitly save to your dashboard, preferences (currency, units, theme), and favorites.
- Feedback:the “was this helpful” rating and any optional comment you submit on a calculator page.
- Usage analytics: if enabled, anonymized/pseudonymous product analytics via PostHog (e.g. which calculators are used), this is optional and off by default in self-hosted deployments.
Calculators you use without an account
You do not need an account to use any calculator on 2xKit. Without an account, your inputs, favorites, and history are stored only in your browser's local storage and are never sent to our servers.
Who we share data with
We use the following third-party processors to run 2xKit. We don't sell your data.
- Supabase, database, authentication, and file storage.
- PostHog, optional product analytics.
- Sentry, optional error monitoring (technical error reports only, not your calculation content).
Your rights
From Dashboard → Settings, you can export a copy of all data associated with your account as a JSON file, or permanently delete your account and all associated data at any time, no need to contact us first. For anything else, email contact@2xkit.com.
Cookies
We use a strictly-necessary session cookie to keep you signed in. We do not use third-party advertising or tracking cookies.

If we make material changes to this policy, we'll update the date at the top of this page and, for significant changes, notify account holders by email.
