Privacy Policy
Last updated: 25 March 2026
1. Who we are
CalcSimplr (“we”, “us”, “our”) is operated by CalcSimplr, based in the United Kingdom.
We are the data controller for the personal data described in this policy.
2. What personal data we collect
We do not collect personal data. All calculations happen in your browser — nothing you type is ever sent to or stored on our servers. The only data we receive is anonymous, aggregated usage statistics (no cookies, no IP addresses) and advertising cookies if you consent to them.
3. Legal basis for processing
- ✓Legitimate interests (Art. 6(1)(f) UK GDPR) — anonymous analytics help us improve the service without identifying you personally.
- ✓Consent (Art. 6(1)(a) UK GDPR) — advertising cookies are only placed after you give explicit consent via our cookie banner. You may withdraw consent at any time.
4. How long we keep your data
Anonymous analytics are retained for up to 90 days. Advertising cookies (if consented) persist for up to 13 months per our ad provider’s schedule.
5. Who we share your data with
We use the following data processors under binding agreements:
| Processor | Role | Location |
|---|---|---|
| Hosting provider | Hosts the site and collects anonymous analytics | USA (SCCs) |
| Advertising provider | Serves ads — only if you consent | USA (SCCs) |
We do not sell your personal data to any third party.
6. International transfers
Our processors are based in the United States. We rely on UK-approved Standard Contractual Clauses (UK SCCs) to ensure your data receives equivalent protection to that required under UK GDPR when transferred outside the UK.
7. Your rights under UK GDPR
Since we collect minimal data, only two rights are practically relevant right now:
- ✓Right to withdraw consent — withdraw your cookie consent at any time via the cookie settings link in the footer. This stops advertising cookies immediately.
- ✓Right to object — object to anonymous analytics processing by contacting us via the site.
When user accounts are introduced, the full set of UK GDPR rights (access, erasure, portability, rectification) will apply and this section will be updated.
8. Cookies
We use the following cookies:
| Cookie | Type | Purpose |
|---|---|---|
| Cookie consent preference | Strictly necessary | Stores your cookie consent choice. Not a tracking cookie. |
| Advertising cookies | Advertising (consent required) | Personalised ads from our ad provider. Only set after you accept. |
You can manage your preferences at any time via the Cookie Settingspage or by clicking “Cookie settings” in the footer.
9. Security
- ✓All data is transmitted over HTTPS (TLS 1.2+)
- ✓We do not store your calculator inputs — all calculations happen in your browser
10. Questions or complaints
If you have questions about this policy or want to withdraw your cookie consent, use the cookie settings link in the footer. You also have the right to complain to the UK ICO.
