What we collect
Anonymous sessions are identified by a signed cookie. Documents you upload are processed to extract activity data (usage figures, dates, amounts). If you provide an email for your free summary, we store it against your session. We store a keyed hash of your IP address for rate limiting — never the raw address.
Retention
Anonymous uploads and their extracted data are deleted 30 days after upload, automatically. Paid report packs are retained for the period stated at purchase.
AI processing
Documents are processed by third-party AI providers under contracts that prohibit training on your data. Current providers: Z.ai (document reading and classification) and DeepSeek (the on-site assistant's chat replies — messages are stripped of email addresses and long numeric identifiers before processing, and the assistant is never given your documents). This list is updated when it changes.
Advertising, analytics and cookies
Our editorial pages (calculators and guides) are ad-supported via Google AdSense. No advertising or analytics code runs before you answer the consent banner; in the EEA/UK, consent is collected under the IAB TCF v2.2 framework via our consent-management platform. If you decline advertising cookies, no advertising code loads at all; declining never restricts the tools. Analytics (Google Analytics 4) runs only with analytics consent, with IP anonymisation, under Google Consent Mode with all signals defaulting to denied. You can change your choices at any time from the cookie settings link in the footer. The upload, processing, and report-delivery flows never carry advertising.
Ad blockers
The free tier is funded by advertising, and our terms ask users not to block it. Where blocking is detected on ad-supported pages we may show a reminder or, on the calculator results, ask you to allowlist us or use the paid ad-free tier. Users who declined advertising consent are never treated as ad-blockers.
Your rights (PDPA)
You may request access to, correction of, or deletion of your personal data at any time via privacy@tc02e.com. Our data protection officer can be reached at the same address.
