Privacy Policy
Last updated: January 2026. The short version: your data stays yours.
1. Local-first calculations
All calculator computations run entirely within your browser. The numbers you enter are never transmitted to, stored on, or visible to our servers.
2. Local storage
We use your browser's local storage to remember recent calculations and UI preferences (like theme). This data remains on your device and can be cleared anytime via the Recent panel or your browser settings.
3. No accounts, no tracking pixels
TheCalculators requires no account. We do not sell, rent, or share personal data because we do not collect it. Aggregate, anonymous usage analytics may be collected to improve the product.
4. Contact form
If you contact us, we use your email solely to reply. We never add you to marketing lists without consent.
5. Changes
If this policy changes materially, we will update the date above and, where appropriate, notify users prominently on the homepage.
