Privacy Policy
Last updated: 8 November 2026
Seensy is a browser extension for Gmail that tells you when an email you sent is opened and when links in it are clicked. This policy explains what we collect, why, who processes it, and how you can delete it. Contact: mridul17chaudhary@gmail.com.
in short
- We know your name and email from Google sign-in, nothing from your inbox.
- For emails you track, we store the subject, recipients, links, and when they were opened or clicked.
- We never store the body of your emails, and we never sell data.
- Email us from your account's address and we delete everything within 30 days.
Information we collect
| What | Details | Why |
|---|---|---|
| Your account | Google email address, name and Google account ID, from Google sign-in | To create your account and show it in the extension |
| Tracked emails | Subject, recipient addresses, Gmail thread ID, the time sent, and each link's address and visible text | To show which email was opened and which link was clicked |
| Opens and clicks | Time, the browser or mail app's user agent, and the country derived from the network address. The network address itself is not stored. | To report opens and clicks, and to filter out mail scanners and your own views |
| Your own views | The time you open one of your own tracked emails in Gmail | So your own views are never counted as the recipient's |
| Early-access list | The email address you enter on our website, the time, and which form you used | To tell you when Seensy is available. We send nothing else to this address. |
| Website visits | Anonymous counts from Vercel Web Analytics (no cookies), and our own events: which button or section of the site was used, the page, the referring website and the time. No email address, name or network address. | To see how many people visit and what they find useful |
| Session data | A session token per signed-in browser (we store only a hash of it) and a random owner key stored in a cookie on our tracking domain | To keep you signed in and recognise clicks on your own links |
What we never collect
- The body, attachments or images of your emails.
- Your inbox, other emails, contacts or calendar. Seensy does not use the Gmail API.
- Anything from emails you send with tracking switched off.
How tracking works
When you send an email with tracking on, the extension adds an invisible 1×1 image and routes each link through our server, which redirects to the original address. When the recipient's mail app loads the image or the recipient clicks a link, our server records the event for you.
Google sign-in
Seensy requests only the openid, email and profile scopes. We use this
information only to identify your account. Seensy's use of information received from Google APIs adheres to
the Google API Services User Data Policy,
including the Limited Use requirements.
Who processes your data
- Cloudflare hosts our server and database.
- Google provides sign-in.
- InboxSDK (by Streak), the library the extension uses inside Gmail, sends error reports and usage events to its own servers.
- Vercel hosts this website and provides its cookieless visit statistics.
We do not sell your data, use it for advertising, or share it with anyone else.
People you email
Seensy records when the people you email open your message or click its links, together with their email address as you entered it. Recipients who prefer not to be tracked can block remote images in their mail app. A recipient can ask us to delete data about them by writing to the contact address above.
Data stored in your browser
The extension keeps your session token, your settings and a short queue of pending updates in the browser's extension storage. Signing out removes the session from that browser.
Retention and deletion
We keep your data while your account is active. Email the contact address from your Google account's address to have your account and all its tracking data deleted; we do this within 30 days. Uninstalling the extension stops all tracking but does not delete data already stored.
Security
All traffic uses HTTPS. Session tokens are stored only as hashes. Access to the database is limited to the Seensy operator.
Children
Seensy is not intended for anyone under 16.
Changes
We will update this page and the date above when this policy changes.
