Privacy Notice

Last updated 2025-08-05

This privacy notice applies to your use of the website, application programming interface ("API"), technology, software, and services (as further described in the TABS Terms of Service) ("Terms") via any platform or device("Services"). The Services are owned, licensed, and operated by Mozilla Corporation (referred to herein as "we," "us," "our," or "Mozilla").

This privacy notice explains what information we collect, share, and process, and why. Your use of the Service constitutes your acceptance of this privacy notice, which incorporates by reference our Terms of Service.

Things you should know

We collect the following information directly from you when you use the Services:

Account information. We may collect personal information, such as your name, username, contact information, and any other information that you provide to us in connection with the creation or administration of your account.
Inputs and Outputs. There are currently no LLM or similar AI-based platforms operated by or affiliated with Mozilla. However, Tabstack allows you to query selected LLMs offered by third parties ("Third-Party Models") by inputting information, queries, documents, media, or prompts (Inputs) to these Third-Party Models through the Services. For those Services, we process your Inputs in order to run them through Third-Party Models and generate results ("Outputs"). We may offer you the ability to store history (including your content and/or Outputs) until you choose to delete it. Where we don't offer such capability, if you abandon a query or navigate away from our site, all Inputs and Outputs will be discarded by your browser and irretrievably lost.
Communications. When you contact us in connection with the Services, we may also collect personal information, such as your username, name, email address, or phone number, as well as any other personal information you may provide to us. You may periodically receive emails, including marketing emails from us. We use third party service providers, such as Sendgrid, for email management. You may opt out at any time to our marketing communications, by clicking the unsubscribe at the bottom of the email or via account settings under "Marketing Preference."

We also automatically receive certain information when you interact with the Services:

Payment Information. When you select one of our paid offerings as described on the Tabstack Plan page, you will provide information and send payment through our third-party payment provider: Stripe. Tabstack receives a record of your payment and certain Stripe account details (including the amount, the stripe customer id, stripe payment intent id, payment date, url of receipt (hosted and authenticated via stripe), and invoice id) and the status of your account. We will also have access to your billing address and last four digits of your credit card. We do not store your full payment details. Please see Stripe's Terms of Service and Privacy Notice for more information.
Browsing History. In order to provide the Services, we process your browsing history (including specific URLs, general browsing categories, and other website interaction data) and web form data. If you opt in to storing your history, as available, we will retain this data for 90 days.
Technical data. We receive basic telemetry data by default, which we use to improve the performance, stability, and security of the Services, including information about your device, including hardware configuration and device operating system; browser information, such as browser type and settings; log files and usage data; and event information, such as errors or crashes. We may also receive additional information about your device, such as country, language, operator and OEM, which we use to prevent fraud and abuse, enforce our terms, and improve the security of the Services.
Location data. Your IP address is temporarily collected as part of our server logs, and automatically deleted after 60 days. We use it to approximate your location to comply with relevant legal and regulatory requirements, as well as for fraud and abuse prevention purposes.
Interaction data. We receive aggregate data about visits to Services websites and other aggregate insights about user interactions with the Services. We use this data to better understand usage of the Services, as well as to add, improve, or remove certain features of the Services. We may also receive HTTP referral data to understand the website or domain that referred you to our site, which we only use for purposes of addressing bugs or other technical issues with our Services. We automatically delete this data after 30 days.
Metrics. We may also use cookies, device information, and IP addresses, along with clear GIFs, cookies, and third party services to securely operate some of the Services, help us understand how users engage with our Services, such as visits to our site and settings preferences, and provide additional functionality. We use:
- Sign in with Google, which places a cookie on your device to assist with sign-in and authentication to the Services. When you sign into the Services, you accept the associated Privacy Policy and Terms of Service from Google.
- Google Analytics to obtain metrics on how users engage with our websites. This helps us to improve site content. For more information about how Google uses your personal information, please visit Google Analytics' Privacy & Security. You can install the Google Analytics Opt-out Browser Add-on to prevent data collection about your visits to the Services and prohibit data transmission to Google Analytics.

We also receive the following information from third parties when you use the Services:

Account data. You may need a Google Account in order to create an account and access the Services. When you log in with your Google Account to access the Services, we receive your name, email address, language preference, and profile picture from Google, and use this information to assist with your account administration and to contact you in relation to the Services, as well as to enforce our Tabstack Terms of Services and Acceptable Use Policy. Use of a Google Account is governed by Google's Privacy Policy and Terms of Service.
Fraud Prevention. We may use third-party technology, Google's Invisible reCAPTCHA, in the background of our website in order to identify fraudulent activity. Use of the Invisible reCAPTCHA is governed by Google's Privacy Policy and Terms of Service.
Model query data. When you use any of the Services that enable you to query Third-Party Models, we may automatically receive a payload back that contains the contents of your query; information about the model queried (such as the name and version number); information about technical problems with processing the query, if any; the number of tokens required to process the query; and the model Outputs in response to the query.

We may also use information about you to find and address violations of our terms of Tabstack Terms of Services or Acceptable Use Policy; investigate suspicious activity; detect, prevent, and combat harmful or unlawful behavior; and otherwise maintain the integrity of our Service.

Information We Share.

We use third parties to provide the Services to you, and have contracted with these companies requiring them to protect your information (Third-Party Services):
