Summary

TTCalc calculators process the data you enter locally in your browser. Other features, including AI photo generation, Google sign-in, and analytics, use backend and third-party services.

Local calculators

Financial inputs such as sale price, COGS, fees, weights, ad spend, and expected returns are processed in your browser. TTCalc does not require an account or send calculator inputs to its backend.

AI photo generation

When you use the AI product photo tool, your prompt and any image you provide are sent through TTCalc's Cloudflare Worker to an image-generation service. The Worker checks daily quota limits. Anonymous quotas are keyed by IP; signed-in quotas are keyed by a Google account identifier. No email address, phone number, full name, or raw JWT is used as a quota key.

Google sign-in

Optional Google sign-in lets us distinguish your personal photo quota from the shared anonymous quota. Google sends a verified identity token to TTCalc's Worker. The signed session is stored locally in your browser. You can sign out at any time.

Analytics

TTCalc uses Google Analytics 4 to measure aggregate page views, tool usage, referrers, and conversion events. We do not send calculator financial inputs, generated prompts, or images to GA4.

Advertising

TTCalc uses Adsterra to display ads. Adsterra and its partners may use cookies, device identifiers, or similar technologies to serve and measure ads. You can manage cookies through your browser privacy controls and review the Adsterra Privacy Policy.
