Stored on your device

Extension privacy, license and support
Privacy notice
July 11, 2026Flintglade does not sell extension data, use it for advertising, build browsing profiles, or use captures and reports to train models. Extension permissions are used only for the feature described in that extension’s listing.
Use of information received from Google APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Sent only for the feature you request
Research tools contact the source you select. GitHub tools contact GitHub and, when requested, public vulnerability services. Monitors retrieve the pages you add. These requests may expose ordinary network metadata to those services under their own policies.
Paid-license data
The license service receives a product identifier and license key for validation. Stripe processes checkout and card details. Flintglade receives purchase identifiers, payment status, and the checkout email needed to deliver and support the license; it never receives a full card number.
Specific sensitive values
A GitHub token, if you choose to provide one, is held in Chrome session storage and sent only to GitHub. License keys stay in local extension storage and are sent only to Flintglade’s validation service. Clipboard content is handled only after an explicit copy, paste, append, or save action.
Retention and deletion
Local records remain until you clear them or uninstall the extension. The license service retains purchase, delivery, refund, and dispute state needed to provide lifetime access and prevent refunded-key reuse. Ask us to review or delete support and purchase-linked personal data where the law permits; financial records may be retained when legally required.
Infrastructure
Chrome provides extension storage. Cloudflare delivers and protects the license service and may process ordinary request logs. Stripe handles checkout. Resend delivers license email. Their own notices govern their processing. Flintglade does not add third-party ad or analytics scripts.
Children and changes
These productivity tools are not directed to children under 13. Material changes to this notice will be dated here and reflected in the affected store listing before new data use begins.
License terms
A Pro purchase is a one-time, lifetime license for the named extension’s current major version. It may be activated on browsers you personally use. The license is not a subscription, does not include unrelated extensions, and may be suspended after a refund, chargeback, fraud, or payment-control bypass. Flintglade is the seller; Google is not the seller. The extension periodically validates the license online and pauses paid features after a 14-day offline grace period until a successful validation is available again.
If a paid feature does not work as described, email us within 30 days of purchase. We will troubleshoot it and, when we cannot make it work, refund the purchase. Applicable consumer rights still apply.
Support
For product, accessibility, privacy, billing, refund, or security questions, email support@flintglade.com. Include the product name, expected result, actual result, and browser version. For billing help, include the Stripe receipt identifier, but never a full card number, password, token, private key, or sensitive captured content.
