Magic Guide Tool does not collect, store, or transmit any personally identifiable information.
What data we handle and where it lives
- Guides, region annotations, vector shapes, settings: stored only in your browser's local storage (chrome.storage.local), remembered per URL, and never leave your device.
- Images you upload (overlays, custom icons): stored only in your browser's local IndexedDB; never uploaded to any server.
- Screenshots: generated locally when you capture or export, used only for display or for writing into the Google Sheet you specify.
Outbound transmission #1: report export (optional)
When you explicitly use "Export report to Google Sheet", your annotation data and screenshots are sent over HTTPS to a Google Apps Script endpoint that you deploy yourself and set to "only myself" access, then written into your own Google Sheet.
- Data does not pass through the extension developer or any third-party server.
- You provide the endpoint URL yourself; the extension only allows the https://script.google.com and https://script.googleusercontent.com domains.
- If you don't use this feature, no data ever leaves your device.
Outbound transmission #2: license validation (optional)
When you explicitly purchase a paid plan and activate a license key, or when your subscription status is re-checked, the extension sends your license key and a randomly generated local device ID over HTTPS to the publisher's self-hosted license proxy (a Cloudflare Worker), which relays them to the payment provider Creem for validation.
- Only the license key and device ID are sent — never any browsing content, guides, annotations, or images.
- This request happens only when you actively activate a key or re-validate; the free version never triggers it.
- The license key is stored only in your browser, used to re-verify that your subscription is still valid.
- Payment itself happens on Creem's hosted checkout page; the extension never sees or stores your card details.
Third parties
This extension uses no analytics, advertising, or tracking services.
