Privacy Policy

What Openly collects, why, who it is shared with, and the choices you and the people you email have.

Last updated 22 October 2026

01Who this covers

Openly (“Openly”, “we”) is a tool that shows you when emails you send from Gmail are opened, how many times, and when. This policy explains how we handle personal data for three groups of people:

  • People who sign in to Openly (“you”, when you use the dashboard and the Gmail extension).
  • People who receive an email that was sent with Openly tracking turned on.
  • People who visit this website without signing in.

For your account we are the controller. For the details of emails you track, including who you sent them to, you decide why and how they are used, and we act as your processor.

02What we collect

DataWhat it includes
AccountThe name and email address on your Google account, Google’s permanent id for it, and the time you first signed in. We never see your Google password, and we never read your mail.
Tracked emailsFor each email you send with tracking on: everyone on To, CC and BCC, the subject line, and when it was sent. We do not receive the body of your email or its attachments, except a PDF you choose to turn into a tracked link (see “Documents” below). If link tracking is on for an email, we receive the web addresses of the links in it (as written, and not the text around them), so we can send visitors on to them.
DocumentsA PDF you upload, or attach in Gmail with the “PDFs” box ticked: the file itself, its name, its size and when you added it. It is kept until you delete it or your account, and anyone who has its link can open it, so only share links with people you mean to.
Document viewsEach time a link to a PDF is opened: the time, the kind of app or browser in broad terms, and for each page how long it was on screen. We do not store the IP address, location or exact device of the viewer. The viewer page tells the reader that the sender can see this. If the sender has chosen it (by default, for emails sent to several people), the page first asks the reader for their email address. We store that address with the view and show it to the sender. It is typed in by the reader and is not verified.
Reminder settingsWhether you want reminders about emails nobody has opened, after how many hours, and whether to also get them by email. For an email you dismissed or snoozed, that choice and when.
Welcome emailWhen you first sign in we send one welcome email to your Google address, with the steps to get started. We note that it was sent, so you only ever get one. It is not a newsletter, and we do not use your address for marketing.
Reminder emailsIf you turn them on, we email your own Google address a short note listing emails of yours that still haven’t been opened: the subject, who it went to and when. Each message has a link to turn these emails off. We send them through an email delivery service (Resend). We keep a record of which reminder went out for which email, so none is sent twice.
Link clicksEach time a tracked link is clicked: the time, a label (“clicked”, “scanner” for an automatic check by a security filter, or “you” for the sender’s own view) and the kind of mail app or browser in broad terms. We do not store the IP address, location or exact device of the person who clicked.
OpensEach time the tracking image loads: the time, a label such as “opened”, “scanner” or “you”, and the kind of mail app that loaded it (Gmail, Outlook, Yahoo Mail, Apple Mail or other). We do not store the IP address, location, or the exact device or browser of the person who opened. The mail app’s identifying text is read for a moment to work out these labels and is not kept.
Extension keysA name you give each key, its last four characters, when it was made and last used, and whether it was revoked. Only a one-way hash of the key is stored, never the key itself.
Sessions and cookiesA hashed sign-in token with its expiry. See “Cookies and storage” below.
Technical recordsOur host, Cloudflare, handles every request to the service, and so sees details such as IP address and user-agent while delivering it. We don’t store these ourselves.

If you use the Gmail extension, it reads the compose window in your browser to find the recipients and subject and to add the tracking image. With the “PDFs” box ticked, when you attach only PDF files to a message, it uploads those PDFs to us (instead of attaching them) and puts a link in the message; with the box unticked, or when other kinds of file are attached too, it does nothing with your files. It sends only the recipients, the subject and, when the “Links” box next to Send is ticked, the web addresses of the links in the message. On Gmail’s list pages it also reads each row’s subject, the addresses shown and the time, on your computer only, to put a tick beside the emails you tracked; that text is compared there and never sent to us. You can switch the ticks off in the extension’s popup. About once a minute the extension also asks Openly for the number of opens and clicks on your tracked emails, to show a green dot on its toolbar icon and a count on the Gmail button; this uses the same key and the same data as the dashboard, and can be switched off in the popup too. The extension can also show a small button in Gmail’s top bar that opens a panel with your latest opens and clicks; it shows the same data, fetched the same way, and reads nothing from the Gmail page except where to put the button. It does not read your inbox or your other mail.

03How we use it

  • To run Openly: sign you in, record your tracked emails and their opens, and show you the results.
  • To keep the service safe: prevent abuse and protect accounts.
  • To contact you about your account if we need to.
  • To meet legal obligations and handle disputes.

We don’t sell personal data, we don’t show ads, we don’t use analytics trackers, and we don’t use your data to train AI models.

04Legal bases (UK and EU)

Where GDPR applies we rely on contract (to give you the service you signed up for) and legitimate interests (security and preventing abuse). For the people who receive a tracked email, the sender relies on their own legitimate interests, and is responsible for any consent that local law requires for tracking technologies.

05Who we share data with

We use these providers to run Openly. They only receive what they need for their part.

ProviderWhy
ResendDelivers the welcome and reminder emails described above to your own address. It receives your address and the text of the reminder.
CloudflareHosting, the network that serves Openly, and the database (Workers and D1) where the data above is stored.
GoogleSigning you in. Google tells us your name and email address when you approve. Your Gmail is your own account, under Google’s terms.
Google FontsThe dashboard and this page load the Inter typeface from Google, so Google can see the visitor’s IP address when the page loads.

We may also share data if the law requires it, to protect people from harm, or in a merger or sale of the business (with notice to you).

06Cookies and storage

NamePurposeLasts
openly_sessionKeeps you signed in. Strictly necessary. HttpOnly.30 days, or until you sign out
openly_oauthProtects the Google sign-in step against forgery. HttpOnly.10 minutes
openly-theme (browser storage)Remembers light or dark.Until you clear it
Extension settings (browser storage)Holds your server address and key inside the Chrome extension.Until you remove the extension or clear it

We don’t use advertising or cross-site tracking cookies.

07International transfers

Cloudflare and Google run services worldwide, so data may be processed outside your country, including in the United States. Where required, we rely on appropriate safeguards such as standard contractual clauses.

08If you received an email sent with Openly

A person sent that email, not us, and they are responsible for it. Openly doesn’t send email and adds no unsubscribe link. To stop receiving emails from the sender, ask them.

How the tracking works. The sender’s email can contain a tiny invisible image. When your mail app loads it, our server records that the email was opened and when. We learn only the time and the kind of mail app that loaded it (for example Gmail or Outlook), and nothing else about you: not your IP address, location or exact device. If an email is opened in more than one kind of mail app, the sender sees a note that it may have been read on another device or passed on. Many mail apps load images automatically, so an “open” does not prove you read the email.

Tracked PDFs. The sender can share a PDF as a link to an Openly viewer page instead of attaching the file. When you open it, our server records the time and the kind of app, and which pages were on screen and for how long. The page says so at the top. For an email sent to several people, the page may first ask for your email address so the sender can tell who opened it; it says that the sender will see it, you can type any address you like, and nobody but the sender sees it. The sender can delete the document at any time, which ends the link.

Tracked links. The sender can also have the links in an email replaced with Openly addresses (on t.tryopenly.com). When you click one, our server records the time and the kind of app, and sends you straight on to the real page. Security filters often click links automatically, so a “click” does not prove a person did. The sender can switch this off for any email.

Your choices. You can stop the image from loading by turning off automatic image loading in your mail app. You can also ask us what we hold about you, or ask us to delete it, by emailing mail@openlee.xyz with the address that was emailed. We will remove the tracked emails that list your address and their opens.

09How long we keep it

  • Tracked emails and their opens: until you ask us to delete them or close your account. We don’t delete them automatically yet.
  • Reminder settings and the record of reminders sent: until you delete the email they belong to or your account.
  • Documents and their views: until you delete the document (on the Documents page) or your account.
  • Sign-in sessions: they expire after 30 days, and signing out ends one immediately.
  • Extension keys: when you revoke one it stops working at once. We keep a record that it was revoked.
  • You can delete your account and all its data yourself, at the bottom of the Extension page in the dashboard; it happens at once. If you ask us by email instead, we do it within 30 days. Backups, if any, age out on a short cycle.

10How we protect it

  • Everything is sent over encrypted connections.
  • We store no passwords, because you sign in with Google. Sign-in tokens and extension keys are stored only as one-way hashes.
  • Every account is separate: you can only ever see your own emails and keys.
  • Changes made from the dashboard are protected against forged requests, and the sign-in step is protected against interception and forgery.

No system is perfectly secure. If a breach affects your data we’ll tell you and the regulator where the law requires.

11If you send emails with Openly

You are responsible for how you use tracking. Depending on where you and your recipients are, the law may require you to tell recipients that you track opens and to get their consent first. Openly does not tell your recipients for you. Don’t use it to track people in ways they would not expect or that the law doesn’t allow.

12Your rights

Depending on where you live, you may have the right to access your data, correct it, delete it, restrict or object to its use, receive a copy, and withdraw consent. You can revoke any extension key yourself on the Extension page. For anything else, email mail@openlee.xyz. You can also complain to your data protection authority.

If you are someone who received a tracked email, we may refer your request to the sender, as they decide how the email is used, but we will help.

13Children

Openly is for adult use and is not directed at anyone under 18. We don’t knowingly collect their data.

14Changes to this policy

We may update this policy as the product changes. We’ll change the date at the top and, for significant changes, tell people with an account by email or in the app.
