Privacy Policy
Last updated: June 13, 2026
This Privacy Policy explains how Markmez ("we", "us", "our") collects, uses and protects your information when you use the Markmez browser extension and website (collectively, the "Service"). By installing or using Markmez, you agree to the practices described here.
1. Information we collect
We keep data collection to the minimum necessary to operate the Service:
- Account information. When you sign in with Google, we receive your Google account email address, display name and profile picture. We use this to create and identify your account. We do not receive your Google password.
- Your content. The boards, pages, bookmarks, notes and settings you create in Markmez are stored locally in your browser (using Chrome's local and sync storage) so the Service can display them back to you and sync them across your devices.
- Payment information. If you purchase a lifetime license, payment is handled by our third-party payment processor. We receive only a transaction confirmation. We do not receive, store or process your credit card number or other payment credentials.
- Usage and technical data. Markmez does not currently use analytics or advertising trackers. If in the future we introduce privacy-friendly, anonymous usage analytics to help us improve the Service (for example, which features are most used), we will update this policy and our Chrome Web Store data disclosure accordingly. Any such data would not personally identify you.
- Weather location. If you enable the weather widget and choose the "use my location" option, your browser requests your geographic coordinates. These coordinates are sent to a weather API to fetch the current forecast and are not stored on our servers beyond the duration of that request.
2. Chrome extension permissions explained
Markmez requests the following browser permissions. We describe exactly why each is needed:
- storage. Used to save your boards, bookmarks and settings locally in your browser and to sync them across your Chrome profile via Chrome's built-in sync storage.
- bookmarks. Requested to allow importing your existing Chrome bookmarks into Markmez boards (optional feature).
- identity. Used exclusively to authenticate you with your Google account using Chrome's built-in OAuth flow. No authentication tokens are sent to our servers.
- activeTab / tabs. Used to read the title and URL of the current page when you save a tab to a board (via the Quick Save button). We do not log, store or transmit your browsing history.
- Access to all websites (host_permissions). When you add a link and Markmez attempts to pre-fill the title, the extension fetches the HTML of the page you provided to extract its title tag. This request is made directly from your browser, not via our servers. No data from visited pages is sent to us or stored beyond the title you choose to save.
Additionally, Markmez fetches website favicons from Google's favicon service (google.com/s2/favicons) to display icons next to your bookmarks. Only the domain name of the bookmarked URL is sent to Google for this purpose.
3. How we use your information
- To provide, maintain and improve the Service.
- To save and sync your boards and bookmarks across your devices via your Chrome profile.
- To process your purchase and provide customer support.
- To communicate with you about important changes, security matters or your account.
- To understand how features are used so we can improve the product.
4. How your data is stored
Your content (boards, bookmarks, settings) is stored primarily in your browser using Chrome's chrome.storage.local and chrome.storage.sync APIs. When you are signed in, sync storage allows your data to follow you across devices where you are signed in to the same Chrome profile. This sync is managed by Google's Chrome sync infrastructure.
We apply reasonable technical and organizational measures to protect any data we do hold against unauthorized access, loss or misuse. However, no method of storage or transmission is 100% secure.
5. Sharing of information
We do not sell, rent or trade your personal data. We do not show ads. We share data only with service providers that help us operate the Service:
- Google (authentication). Used for sign-in via Google OAuth.
- Payment processor. Used to handle purchase transactions securely.
- Hosting provider. Used to host the Markmez website and any server-side components.
- Weather API. Receives geographic coordinates to return a weather forecast when you enable the weather widget with location access.
These third parties are only permitted to use your data to perform services on our behalf and are not allowed to use it for their own purposes.
6. Your rights and choices
- Export. You can export the data you have added to Markmez at any time from within the extension settings.
- Deletion. You can request deletion of your account and any associated server-side data by contacting us at markmezapp@gmail.com. Local browser data can be cleared at any time by uninstalling the extension.
- Access. You can ask us what personal data we hold about you.
- Withdraw consent. You can revoke Markmez's access to your Google account at any time from your Google Account security settings.
7. Data retention
We retain your account information and any server-side data for as long as your account is active. If you request account deletion, we will remove your associated data within 30 days, except where we are required to keep certain records by applicable law.
8. Children
Markmez is not directed to children under 13 years of age, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.
9. International users
Your information may be transferred to, stored and processed in a country different from the one in which you reside. The third-party providers we rely on (such as Google, our payment processor and our hosting provider) may process data in various countries. By using the Service, you consent to your information being transferred and processed in this way.
10. Changes to this policy
We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page and, where appropriate, notify you within the extension or by email.
