Leanr Ads Ltd (“Leanr Ads”, “Leanr”, “we”, “us”, “our”) respects your privacy and is committed to protecting personal data in accordance with the UK GDPR, EU GDPR, and applicable data protection laws.
This Privacy Policy explains how we process personal data when you:

4. Legal bases for processing
- Consent — where required for device storage or analytics

- Legitimate interests — security, fraud prevention, debugging and service integrity
- Legal obligation — compliance with applicable laws and regulatory requests
5. IAB TCF and advertising privacy
Leanr Ads supports the IAB Europe Transparency & Consent Framework (TCF). Where a TCF-compliant Consent Management Platform (CMP) is in place, consent and legitimate interest signals may be passed to Leanr via the TC string.
In advertising contexts, the Data Controller (typically the publisher, advertiser or platform) determines which purposes and legal bases apply. Leanr processes data strictly in accordance with the controller’s instructions and applicable contracts.
If required consent is missing or invalid, our systems may limit processing to what is strictly necessary for delivery, security or error prevention.
6. Cookies and similar technologies
Leanr uses cookies and similar technologies only where necessary and as described in our Cookie Policy. Cookies are not required for core creative delivery and are treated as optional, best-effort mechanisms.
7. Data sharing
We may share personal data with:
- Infrastructure and hosting providers
- Security, monitoring and analytics service providers
- Professional advisers (legal, accounting)
- Clients, where required to deliver contracted services
- Authorities, where legally required
8. International transfers
Where personal data is transferred outside the UK or EEA, appropriate safeguards are used, such as adequacy decisions or Standard Contractual Clauses.
9. Data retention
We retain personal data only for as long as necessary for the purposes described above. Typical retention periods include:
- Website enquiries: up to 12 months
- Client and contractual records: contract term plus legal requirements
- Creative server event and security logs: short-lived where feasible, typically days or weeks, and no longer than necessary for measurement, security or audit purposes
10. Your rights
Where Leanr Ads acts as a Data Controller, you may have the right to access, rectify, erase, restrict or object to processing, and to withdraw consent where applicable.
To exercise your rights, contact tom@leanrads.com. You also have the right to lodge a complaint with the UK Information Commissioner’s Office (ICO).
Processor note: Where Leanr acts as a Data Processor, rights requests should be directed to the relevant Data Controller. We will assist controllers as required under our contracts.
11. Security
We implement appropriate technical and organisational measures to protect personal data, including access controls, secure infrastructure, monitoring, and least-privilege practices.
12. Children
Our services are not directed at children and we do not knowingly process personal data relating to individuals under 16.
