Sellerline runs entirely in your browser. Nothing you type into any tool, product costs, fees, or shop details, is sent to a server or stored anywhere except your own device's local storage, and only when a tool explicitly saves something for you. There is no account system and no backend database, so there is nothing on our end to lose, leak, or subpoena.
What we do collect
Hosting and basic traffic logs (Cloudflare): our host automatically logs standard technical information for every visit, such as IP address, browser type, and pages requested, for security and aggregate traffic reporting. This is normal web server behavior and is not tied to any account, because there are no accounts.
Advertising (Google AdSense): Sellerline is free to use and partly supported by ads served through Google AdSense. Google and its advertising partners may use cookies to serve ads and measure performance, which can include personalizing the ads you see. You can control ad personalization through Google's Ad Settings.
Payments (Stripe): if you choose to upgrade to obscuraos.com Pro, payment is handled entirely by Stripe on Stripe's own secure checkout page. We never see, receive, or store your card number or other payment details, Stripe processes and retains that information under Stripe's Privacy Policy. Stripe shares limited transaction status with us (such as "payment succeeded") so your browser can unlock paid features, nothing more.
Contact form (if used): if you email us or use the contact page, we receive whatever you choose to send, an email address and message, so we can reply. We don't add you to any marketing list from that alone.
Local storage
Tools on this site use your browser's built-in local storage to remember things you've entered, so you don't have to redo them every visit. This data stays on your device, it is never uploaded to us. Clearing your browser's site data, or switching browsers or devices, will clear it, since nothing is backed up anywhere else.
Cookies
Sellerline itself does not set tracking cookies. The third-party services above, Google AdSense in particular, may set their own cookies as described in their respective policies linked above.
Children's privacy
Sellerline is a business tool intended for working adults, and is not directed at children. We do not knowingly collect information from anyone under 13.
