Privacy Policy

Last updated: May 21, 2025

1. Overview

toksum.dev ("we", "our", "us") operates the AI API cost calculator at https://toksum.dev. This policy explains what information we collect, why we collect it, and how we handle it.

We are committed to collecting as little data as possible. All cost calculations run entirely in your browser — no inputs are sent to our servers.

2. Information We Collect

2a. Analytics (Cloudflare Web Analytics)

We use Cloudflare Web Analytics to understand how visitors use our site. Cloudflare Analytics is privacy-first: it does not use cookies, does not track individuals across sites, and does not sell data. It collects aggregated metrics (page views, referrers, browser type, country).

2b. Calculator Inputs

All token counts, model selections, and cost estimates you enter are processed locally in your browser. We do not store or transmit these values.

2c. Pro Account (if applicable)

If you create a Pro account, we collect your email address for authentication and billing via our payment processor (Polar.sh or Stripe). Payment card details are handled exclusively by the payment processor and are never stored on our servers.

3. Cookies

We do not set tracking or advertising cookies. If you create an account, a session cookie is used to keep you logged in. This cookie is strictly necessary and expires when you close your browser or log out.

4. Third-Party Services

Cloudflare — CDN, DDoS protection, and analytics. Cloudflare Privacy Policy
Polar.sh / Stripe — payment processing for Pro subscriptions.
Google AdSense (planned) — may display personalized ads. You can opt out via Google Ad Settings.

Affiliate links on this site may earn us a commission at no extra cost to you. See our Affiliate Disclosure.

5. Data Retention

Cloudflare Analytics data is aggregated and anonymized — no personal data is retained. If you delete your Pro account, all associated data is permanently deleted within 30 days.

6. Your Rights

Depending on your location, you may have rights under GDPR (EU), CCPA (California), or similar laws, including the right to access, correct, or delete your personal data. To exercise these rights, contact us at the address below.

7. Changes to This Policy

We may update this policy. Material changes will be noted with an updated "Last updated" date at the top of this page.
