5. Our lawful bases

Under UK data protection law, we need a lawful basis to use personal information. Depending on the circumstances, we may rely on:

Contract

Where processing is necessary to provide Mattr and perform our agreement with you, including account management, profiles, networking, messaging, events and introductions.

Legitimate interests

Where necessary for our legitimate interests or those of other users, provided those interests are not overridden by your rights. These interests may include improving relevance and recommendations, keeping Mattr secure, preventing fraud and misuse, improving the service, understanding product performance and enabling useful professional connections.

Consent

Where you have actively given consent, including where consent is required for certain marketing or non-essential cookies or similar technologies.

Legal obligation

Where we need to process information to comply with a legal or regulatory requirement.

6. Information other users can see

Mattr is a networking platform. Information you add to your profile or publish may be visible to other members depending on the relevant feature and your account or privacy settings.

This may include your name, profile photograph, professional information, interests, biography, connections or mutual connections, event participation and content you publish.

Private messages are not intended to be publicly visible. You should only share information you are comfortable providing to the people who can access it.

7. Recommendations and Mattr Intelligence

Mattr may use profile information, network relationships, mutual connections, shared interests, event activity and other relevant signals to recommend people, events or introductions.

These recommendations are intended to help you discover relevant people and opportunities. They do not guarantee that another user is suitable for you, an introduction will result in a connection, an event will be relevant, or a commercial or professional opportunity will arise.

You remain responsible for deciding whether to connect, communicate, meet or engage with another user.

8. Who we share information with

We may share personal information with service providers that help us operate Mattr, including providers of cloud hosting and content delivery, authentication, databases and infrastructure, email and communications, security and monitoring, customer support, and analytics where used.

Current infrastructure includes service providers such as Cloudflare and Supabase.

We may also disclose information where required by law; to regulators, courts or law-enforcement bodies where legally required; to protect users, Mattr or others from harm, fraud or illegal activity; or as part of a corporate transaction such as a merger, investment, acquisition or sale, subject to appropriate safeguards.

We do not sell your personal information to advertisers.

9. International transfers

Some service providers may process information outside the United Kingdom. Where personal information is transferred internationally, we will use an appropriate legal mechanism where required, such as UK adequacy regulations, the UK International Data Transfer Agreement, the UK Addendum to approved standard contractual clauses, or another lawful transfer mechanism.

10. How long we keep information

We keep personal information only for as long as reasonably necessary for the purpose for which it was collected.

In determining retention periods, we consider whether your account remains active; whether information is needed to provide the service; security and fraud-prevention requirements; legal and regulatory obligations; potential disputes or legal claims; and technical backup and disaster-recovery requirements.

When information is no longer required, we will delete or anonymise it where reasonably practicable.

11. Account closure

You may request closure of your account. Some information may remain for a limited period where necessary for security, fraud prevention, legal obligations, resolving disputes, enforcing agreements or backups.

Content shared with or sent to other users may not always be capable of being withdrawn from copies legitimately held by those users.

12. Your data protection rights

Depending on the circumstances, UK data protection law may give you rights including access to your personal information, correction of inaccurate information, deletion of your information, restriction of processing, objection to processing, data portability and withdrawal of consent where processing relies on consent.

To exercise a right, contact privacy@mattr.network. We may need to verify your identity before responding.

13. Right to object

Where we rely on legitimate interests, you may have the right to object to the processing of your personal information.

You also have an absolute right to object to the use of your personal information for direct marketing. Contact privacy@mattr.network to exercise this right.

14. Marketing

Where permitted, we may send service updates or marketing communications about Mattr. You can unsubscribe from marketing communications at any time using the unsubscribe mechanism provided or by contacting us. Service messages necessary to operate your account may still be sent.

15. Cookies and local storage

Mattr may use cookies, browser storage and similar technologies that are strictly necessary for authentication, session management, security, preferences and core service functionality.

If we use non-essential analytics, advertising or similar technologies that require consent, we will request consent before setting them.

16. Security

We use appropriate technical and organisational measures designed to protect personal information.

No online service can guarantee absolute security, and you are responsible for protecting your login credentials and using a secure password. Please contact us if you believe your account or information has been compromised.

17. Children

Mattr is intended only for users aged 18 and over. Users must not create an account if they are under 18.

18. Reporting content and safety

Users may report content, accounts or behaviour that they believe is illegal, harmful or breaches Mattr's Terms.

We may investigate reports and take action including restricting content, removing content, limiting functionality, suspending accounts, terminating accounts and making legally required reports to relevant authorities.

Where Mattr is subject to duties under the Online Safety Act 2023, we will maintain proportionate systems and processes required by applicable law.

19. Changes to this policy

We may update this Privacy Policy as Mattr develops or legal requirements change. Where a change is significant, we may provide additional notice. The latest version will always be published on Mattr.

20. Complaints

If you have concerns about how we use your personal information, please contact privacy@mattr.network.

You also have the right to complain to the Information Commissioner's Office.
