Privacy Policy
Last updated: October 1, 2026
OneFile Tools ("we") sells downloadable HTML tools. This policy explains what data we collect and why. The short version: our tools run entirely in your browser and collect nothing; we only handle the minimum data needed to sell and support them.
1. Data we collect
- Purchase information: when you buy, our payment provider Creem processes your payment and shares your name, email address, and order details with us so we can deliver your download and provide support. We never see or store your full card number.
- Support emails: if you contact aton99980@gmail.com, we keep your message so we can help you.
- Website analytics: we may use privacy-friendly, cookie-less analytics to understand aggregate visits. No cross-site tracking, no ad profiling.
2. Data our tools collect
None. The tools are single HTML files that run locally in your browser. Invoices, clients, and time entries are stored in your browser's local storage on your own device. Nothing is transmitted to us or any third party.
3. How we use your data
To deliver your purchase, send update notifications, provide support, and comply with legal obligations (e.g., tax records kept by Creem as merchant of record).
4. Sharing
We share purchase data only with Creem (payment processing) and our email provider (delivery and support). We do not sell your data.
5. Your rights
You can request a copy, correction, or deletion of your personal data at any time by emailing aton99980@gmail.com.
6. Contact
