This policy applies to the CALCOPT website (the "Service").
1. Information we collect
Calculator inputs (travel dates, income, dates of birth, etc.) are processed inside your browser and are never sent to our servers unless you explicitly choose to save them. If you use the save/alert features, we collect your email address (login is via magic link; we never store passwords) and the data you save. With your consent, we use Google Analytics 4, which sends analytics-cookie identifiers, page URLs, browser/device information, and approximate location to Google LLC. Without consent, we do not load the GA4 tag or store analytics cookies.
2. Purposes
- Providing save/restore and email alerts
- Operating and improving the Service; fixing issues
- Preventing abuse; responding to inquiries
- Complying with law
We do not sell personal data or share it for third-party advertising.

4. Cookies
We set only an authentication cookie for logged-in users. Google Analytics 4 stores analytics cookies such as `_ga` only after you grant analytics consent. You can change or withdraw consent through Cookie Settings in the footer; withdrawal deletes analytics cookies and prevents the tag from loading. Links labeled "PR" are affiliate links; the advertiser's network may set cookies after you leave our site.
5. Retention, deletion, and your rights
Saved data is kept while your account exists. Contact pakutichi@gmail.com to request deletion, access, correction or restriction of your data.
6. EEA / UK users
Our legal bases are performance of contract and legitimate interests. You have rights of access, correction, deletion, restriction and portability.
