Supergroup

Privacy Policy

1. Introduction

Supergroup ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website, mobile applications, and related services (collectively, the "Service"). By using the Service, you consent to the practices described in this policy.

2. Information We Collect

Information you provide:

Information collected automatically:

Information from your device, only if you allow it:

Information from services you connect:

3. How We Use Your Information

We use the information we collect to:

4. AI and Groupie

AI is part of how Supergroup works, not an add-on. Groupie, an AI participant, is built in: it reads along in your conversations so it can answer questions and help out, and several other features run on AI models behind the scenes. Some of this happens automatically, whether or not you've asked Groupie anything. This section explains what is sent, when, and to whom.

We ask before anything is sent. Before any of your data goes to an AI provider, the app asks for your permission, during sign-up or sign-in, and explains what is sent and to whom. Because AI is a core part of the Service, Supergroup can't be used without agreeing. If you change your mind, you can delete your account at any time.

Groupie reads along to decide whether it can help. Each time a message is sent in any conversation, including one-to-one chats, that message, the roughly 20 messages before it, and the display names of the people who wrote them are sent to an AI model from OpenAI, which decides whether Groupie should respond.

When Groupie responds. Groupie responds when you ask it to (by mentioning @groupie, tapping Ask Groupie, messaging it directly, or replying to it), or when it decides it can help. To write its response, the AI model receives:

Groupie can act in the conversation: it can reply, react to messages, pin messages, and post cards such as weather, places, flights, sports scores, and calendar events. Everything it posts is visible to the people in that conversation. So that Groupie can remember what a long conversation has covered, older parts of it may be summarized by an AI model.

Photos and search. These happen automatically, so that you can find things later:

Groupie's tools. To look things up, Groupie sends search queries — not your messages wholesale — to the services that answer them: SearchApi.io for web and shopping search, Google Maps Platform for places, FlightAware for flights, and eBird for birds. Images Groupie generates are made by OpenAI. Link previews may be fetched through iframely (see Section 5).

Our AI providers. We use OpenAI (including its GPT models, through OpenAI's API), Google (its Gemini models, through Google Cloud's Vertex AI), and Amazon Web Services (AWS) Bedrock, which runs models from Anthropic (Claude), Amazon (Titan and Nova), and others. There's no model picker in the app; we choose which model handles each job. These providers process your data only to provide the Service to us, under terms that protect it as this policy does, and not for their own purposes. Per the AWS Bedrock terms of service, AWS does not retain this data or use it to train its models. Per Google Cloud's terms, Google does not use this data to train its models. OpenAI processes API data under its applicable API data-use and retention terms and does not use API data to train its models by default.

AI-generated responses and images are posted to the conversation they belong to, and are stored and retained like any other message (Section 12).

5. Link Previews

When you or another user shares a URL in a conversation, our servers fetch the destination page, sometimes through the link-preview service iframely, to generate a preview (title, description, and thumbnail image). The destination website sees a request from our servers, not from your device, so your IP address is not exposed to the linked site as a result of preview generation.

6. User Reports and Moderation

You can report or block anyone from their profile in the app. A report contains the user you're reporting, the reason you pick (spam, harassment, inappropriate content, or other), and any details you choose to write. It's delivered to our internal moderation channel, which is hosted by Slack Technologies, Inc. on our behalf. When you block someone, that's logged to the same channel too, so we can spot patterns of abuse.

We review every report within 24 hours. Supergroup has zero tolerance for objectionable content and abusive users (see our Terms of Service): when we find objectionable content, we remove it, and we remove the account of the user who posted it. Your block list is stored on our servers, and other users can't see it.

7. Connected Calendars

The Service includes an optional scheduler feature that helps people in a conversation find a time to meet. To improve its suggestions, you may choose to connect a calendar: a calendar account, such as Google Calendar, or, on iPhone, the calendars already on your phone. Connecting a calendar is entirely optional: the scheduler works without it, and you can disconnect at any time.

When you connect a Google Calendar account, you grant Supergroup permission to:

Calendars on your iPhone. On iPhone you can also use the calendars already on your phone — iCloud, Exchange, or anything else the Calendar app shows. There is no account to sign in to. Your iPhone asks whether Supergroup may access your calendars, and the app reads them on your device. Three things leave your phone:

Adding and changing events on your iPhone. Supergroup adds or changes an event on your phone's calendars only when you ask it to, or when you tap a button that says it will: “Add to cal” on an event, or locking in a time on a scheduler or a poll. The app on your iPhone makes the change; our servers cannot reach your calendars. When you ask Groupie to add an event, the app adds it. When you ask it to change or delete one, the app shows you the event and waits for you to confirm. An invitation is answered by you, on your iPhone's own event screen. To do any of this, the details of what you asked for — the event's title, time, place, and notes — pass through our servers to your phone as part of that conversation, visible only to you. They stay with that message until your phone has answered — for a change or a delete, until you tap — and Supergroup's reply then takes their place. An event added this way goes on your calendar only: no invitations are sent. A calendar you've switched off in Settings → Connected Accounts is never written to.

You can stop at any time from Settings → Connected Accounts, which deletes the busy times we hold. If you turn off calendar access for Supergroup in your iPhone's Settings instead, nothing more is sent, and the app disconnects the calendars and deletes those times the next time it checks, usually when you next open it.

We read your calendar only when you ask for something that needs it, and only for the period your question covers. Answering means sending those events to our AI providers, under the terms in Section 4 — they do not train on them. We change your calendar only when you ask us to, never on our own initiative.

We don't keep a separate copy of your events. But the answer itself is a message: it's stored with the rest of that conversation's history and retained on the same terms as any other message (Section 12). That also means if you ask about your schedule in a group conversation, the answer is visible to the people in it — the same as anything else said there. Ask in a one-to-one conversation if you'd rather it stay between you and Supergroup.

To provide this feature, we store the OAuth access and refresh tokens Google issues when you connect. These are encrypted at rest and used only for the purposes above. You can disconnect at any time from Settings → Connected Accounts, or revoke our access from your Google Account permissions page; either way we revoke the tokens and delete them from our systems.

Supergroup's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements. We use Google user data only to provide the features described above. We do not use it for advertising, we do not sell it, and neither we nor our providers use it to train machine-learning models. We do not transfer it to anyone except as needed to provide those features, to comply with applicable law, or to protect against security threats. No one at Supergroup reads your Google user data except with your explicit consent, where necessary for security, or where the law requires it.

8. Contacts

Finding friends from your contacts is optional. The app asks for access once, right after you finish signing up, and after that only if you tap to see who's on Supergroup. If you've said no before, it doesn't ask again. You can turn access off at any time in your device's settings. Inviting someone by picking them from your contacts doesn't need this access at all.

Once you allow access, the app checks your contacts when you open the home screen or start a new chat, at most every 15 minutes. Each check sends the phone numbers and email addresses in your contacts to our servers over an encrypted (TLS) connection. We compare them against the verified phone numbers and email addresses of Supergroup accounts and send back the matches: each person's name, username, and profile photo. We don't store the contacts you send, we don't keep a record of who matched whom, and we don't use your contacts for anything else — not to suggest you to other people, not for advertising, and not to contact anyone. Only accounts that have verified that phone number or email can be matched.

If you invite someone who isn't on Supergroup by phone, the invitation text goes from your own phone, not from us. So that we can recognise them when they sign up, we keep the name you gave them and a one-way code (an HMAC) in place of their number — never the number itself. The invitation expires after 30 days.

9. Location

Supergroup asks for your location only when a feature you're using needs it, and only while you're using the app. We never collect it in the background, and we don't save it to your account. You can decline, and you can change the permission at any time in your device's settings. Two features use it:

10. How We Share Your Information

We do not sell your personal information to third parties, and we never share your phone number or text-message opt-in data with third parties or affiliates for marketing. We share your information in the following circumstances:

11. Data Storage and Security

Your data is stored on Amazon Web Services (AWS) infrastructure in the United States. We implement appropriate technical and organizational measures to protect your information, including encryption at rest and TLS encryption for all data in transit. Credentials for connected calendar accounts are additionally encrypted before storage. However, no method of transmission over the Internet or electronic storage is 100% secure.

12. Data Retention

We retain your personal information for as long as your account is active or as needed to provide the Service. Credentials for a connected calendar account are retained only until you disconnect that account, after which they are revoked and deleted. The busy times from the calendars on your iPhone are replaced each time the app refreshes them, and deleted when you disconnect. If you request deletion of your account, we will delete your personal data within 30 days. Some data may be retained in encrypted backups for up to 90 days. We may retain anonymized or aggregated data indefinitely for analytical purposes.

13. Your Rights and Choices

Depending on your location, you may have the following rights:

To exercise any of these rights, please contact us at support@supergroup.chat.

14. Children's Privacy

The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we learn that we have collected personal information from a child under 13, we will take steps to delete such information promptly.

15. Third-Party Links

The Service may contain links to third-party websites or services. We are not responsible for the privacy practices of these third parties. We encourage you to review the privacy policies of any third-party services you access.

16. International Data Transfers

Your information may be transferred to and processed in countries other than your own. By using the Service, you consent to the transfer of your information to the United States, where our servers are located.

17. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by posting the updated policy on the Service and updating the "Last Updated" date. We encourage you to review this policy periodically.
