Terms of Approval and
Seal Usage Guidelines

Version 1.0  |  July 2026
Important: CDWF Approval records the outcome of an independent assessment at a particular point in time. It is not a guarantee that an Approved Subject is free from all risk, and it is not legal advice, regulatory approval or government endorsement.

1. Purpose and application

These terms apply to every person or organisation that applies for or holds CDWF Approval from TDA. They govern the assessment relationship, the continuing obligations attached to Approval, and the licence to use the CDWF Approved Seal.

CDWF Approval may be awarded to a product, a defined body of content, an individual or a team. Approval applies only to the exact subject identified in TDA's written decision notice.

These terms should be read alongside TDA's current CDWF Assessment Methodology, Appeals and Complaints Policy, Data Protection and Privacy Policy, and Fee Schedule. If a policy conflicts with these terms, these terms prevail unless the policy expressly states that it replaces a specified provision.

2. Definitions

Approval

The binary status awarded by TDA where an Approved Subject has met the applicable CDWF requirements at the time of assessment.

Approval Holder

The organisation or individual named in the decision notice and legally responsible for complying with these terms. The Approval Holder may also be the Approved Subject.

Approved Subject

The specific product, content, individual or team assessed and named in the decision notice.

Assessment

TDA's evaluation of an applicant against the CDWF requirements using the assessment route appropriate to the type of Approved Subject.

CDWF

The Children's Digital Wellbeing Framework.

Content

A clearly defined body of digital or digitally distributed material, which may include a programme, episode, series, channel, publication, learning resource, game content, platform content or other material specified in the decision notice.

Decision Notice

TDA's written notice confirming whether Approval has been awarded, the Approved Subject, the date of the decision, any conditions and the expiry date.

Material Change

A change that may reasonably affect whether the Approved Subject continues to meet the CDWF requirements, including significant changes to features, content, ownership or control, age targeting, data practices, monetisation, social functionality, safeguarding arrangements, AI systems, professional role or team composition.

Seal

The official CDWF Approved graphic, in any variant authorised and supplied by TDA.

TDA

Thrive Digital Alliance.

Validity Period

The 24-month period beginning on the date of the decision notice, unless a different period is stated in that notice.

3. Nature and scope of CDWF Approval

3.1 What Approval means

CDWF Approval means that TDA independently assessed the Approved Subject and found that it met the applicable CDWF requirements at the time of assessment.

3.2 What Approval does not mean

CDWF Approval does not constitute:

  • a guarantee that the Approved Subject is free from harm or suitable for every child or every circumstance;
  • legal, medical, clinical, safeguarding or regulatory advice;
  • approval, certification or authorisation by a government body or regulator;
  • an endorsement of the Approval Holder's organisation, portfolio, employees, clients or other products or content;
  • a promise that the Approved Subject will continue to meet the CDWF requirements after it changes; or
  • a permanent endorsement.

3.3 Subject-specific scope

Approval is limited to the Approved Subject as described in the decision notice. It does not automatically extend to related products, later versions, additional episodes or content, other members of an organisation, replacement team members, adaptations, localisations or derivative works.

4. Application and assessment

4.1 Accurate and complete information

The applicant must provide information that is accurate, complete and not misleading. The Approval Holder must promptly correct any material error or omission identified during or after the assessment.

Deliberate or negligent misrepresentation may result in rejection, suspension or revocation. TDA may treat an Approval as invalid from the date it was awarded where the decision materially depended on inaccurate, incomplete or misleading information.

4.2 Assessment route

TDA will use the assessment route appropriate to the Approved Subject. Depending on the route, this may include document validation, expert review, interviews, demonstration, observation, user or child testing, reference checks, sampling of content, or other proportionate evidence-gathering.

Not every assessment method will apply to every product, body of content, individual or team. The relevant methodology and evidence requirements will be confirmed during the application process.

4.3 Cooperation

The applicant and Approval Holder must provide reasonable access to information, materials, systems and personnel needed to complete the assessment and any subsequent review.

4.4 Assessment decision

TDA may award Approval, refuse Approval, request further evidence, or award Approval subject to clearly stated conditions. Approval remains binary: the Approved Subject is either Approved or not Approved.

5. Award and validity of Approval

5.1 Decision notice

Approval takes effect only when TDA issues a decision notice. The notice will identify the Approval Holder, the Approved Subject, any applicable conditions, the start date and the expiry date.

5.2 Validity

Unless the decision notice states otherwise, Approval is valid for 24 months. Approval remains subject to these terms, any conditions in the decision notice, and the Approved Subject's continuing compliance.

5.3 Public register

TDA may publish the name and description of an Approved Subject, the Approval Holder, the date of Approval, the expiry date and the current status of the Approval. TDA will not publish confidential assessment material or detailed scores without consent, except where required by law or necessary to correct a misleading public claim.

6. Using the CDWF Approved Seal

6.1 Licence

On award of Approval, TDA grants the Approval Holder a non-exclusive, non-transferable, royalty-free licence to use the Seal solely in connection with the Approved Subject during the Validity Period and in accordance with these terms.

The licence permits use of the Seal; it does not transfer ownership of the Seal, the CDWF name or any other intellectual property.

6.2 Authorised third-party display

The Approval Holder may provide official Seal files to a retailer, distributor, publisher, app store, platform, agency, event organiser, client or other service provider solely to identify or promote the Approved Subject. This is not a transfer of the licence. The Approval Holder remains responsible for ensuring that every third-party use complies with these terms.

6.3 Where the Seal may be displayed

Subject to these terms, the Seal may be used in:

  • digital and print marketing materials;
  • product or content listings and packaging;
  • websites and dedicated trust or information pages;
  • app store, platform and marketplace listings or screenshots;
  • press releases and media materials;
  • professional profiles or team pages, where the individual or team is the Approved Subject; and
  • procurement and tender submissions.

6.4 Approved Seal files

Only current Seal artwork supplied or expressly authorised by TDA may be used. TDA may provide full-colour, white, monochrome, compact or other approved variants in formats suitable for digital and print use.

6.5 Technical display requirements

  • Minimum size: 24 pixels for digital use and 10 mm for print.
  • The Seal must remain legible and must not be stretched, compressed, cropped, redrawn or distorted.
  • Clear space must be maintained around the Seal equal to the height of the 'T' in 'Thrive' on all sides.
  • The full-colour Seal should be used on white or light backgrounds; the white Seal should be used on dark or coloured backgrounds.
  • The monochrome Seal may be used where colour reproduction is unavailable.
  • The Seal must not be manually recoloured or placed on a background that makes it unclear or illegible.

6.6 Exact scope

The Seal must appear only in direct connection with the Approved Subject. Where a page, package, catalogue, profile or campaign includes other products, content, individuals or teams, the presentation must make clear which specific subject is Approved.

7. Permitted statements about Approval

7.1 Acceptable wording

Examples of acceptable wording include:

  • "[Name] has been independently reviewed and Approved by Thrive Digital Alliance under the Children's Digital Wellbeing Framework (CDWF)."
  • "[Name] is CDWF Approved by Thrive Digital Alliance."
  • "Approved by Thrive Digital Alliance following independent assessment against the CDWF requirements."
  • "Independently reviewed and Approved for children's digital wellbeing under the CDWF."

7.2 Conditions on claims

Any statement about Approval must:

  • refer only to the Approved Subject;
  • identify TDA as the approving body, or appear directly alongside the Seal;
  • be accurate, current and capable of being substantiated by the decision notice;
  • avoid implying approval by a government body, regulator or any organisation other than TDA; and
  • avoid extending Approval to future, unreleased, materially changed or unassessed versions, content or people.

8. Prohibited and misleading uses

The Approval Holder and any person using the Seal on its behalf must not:

  • use the Seal after Approval has expired, been suspended or been revoked, except during an extension expressly granted by TDA;
  • apply the Seal or an Approval claim to anything other than the Approved Subject;
  • alter the Seal's colours, proportions, wording or design, or add text, filters or effects to it;
  • combine the Seal with another logo in a way that implies partnership, co-ownership or joint endorsement by TDA;
  • state or imply that the Approved Subject is 'certified safe', 'fully safe for children', 'government approved', 'regulator approved' or guaranteed to produce a particular outcome;
  • use 'TDA-endorsed' or similar language to imply a broader commercial, organisational or professional endorsement;
  • use the Seal in a legal or regulatory submission in a way that implies regulatory status;
  • use the Seal or Approval claim in a misleading, deceptive, defamatory or unlawful way; or
  • register or attempt to register the Seal, the CDWF name, or a confusingly similar logo, domain name, account name or identifier.

9. Ongoing obligations

9.1 Notification of changes and concerns

The Approval Holder must notify TDA in writing within 14 days of becoming aware of:

  • a Material Change to the Approved Subject;
  • a regulatory investigation, enforcement action or material legal claim concerning the Approved Subject;
  • a significant safeguarding, safety, data protection or wellbeing concern;
  • a significant complaint or pattern of complaints relevant to the CDWF requirements;
  • a change of ownership or control that may affect responsibility for the Approved Subject; or
  • any public use of the Seal or Approval claim that is materially inaccurate or unauthorised.

9.2 Conditions and good faith

The Approval Holder must comply with any conditions in the decision notice within the specified timeframe and must continue to operate in good faith in accordance with the CDWF principles.

9.3 Material changes

TDA may decide that a Material Change does not affect Approval, requires additional evidence, requires partial or full reassessment, or justifies temporary suspension while the change is reviewed. The Approval Holder must not represent a materially changed subject as Approved unless TDA confirms that the Approval continues to apply.

9.4 Spot reviews

TDA may conduct proportionate spot reviews during the Validity Period, including unannounced reviews of publicly accessible material. The Approval Holder must cooperate and provide reasonable evidence requested by TDA.

9.5 Reporting misuse

The Approval Holder should report suspected misuse of the Seal or a false claim of CDWF Approval to brand@thrivedigitalalliance.org.

10. Renewal, suspension, revocation and expiry

10.1 Renewal

Renewal requires a new assessment. Applications should normally be submitted at least three months before expiry. TDA does not guarantee that a late application will be completed before the current Approval expires.

10.2 Temporary extension

Where a complete renewal application is under assessment at the expiry date, TDA may, at its discretion, extend the existing Approval and Seal licence for up to three months, provided that no material concern has been raised.

10.3 Grounds for suspension

TDA may suspend Approval where:

  • a material complaint or concern is under investigation;
  • a condition has not been met;
  • a Material Change may affect compliance;
  • the Approval Holder has failed to cooperate with a review;
  • the Seal or an Approval claim has been misused; or
  • temporary suspension is reasonably necessary to protect children, the public or the integrity of the CDWF.

10.4 Grounds for revocation

TDA may revoke Approval where:

  • material misrepresentation is confirmed;
  • the Approved Subject no longer meets the applicable CDWF requirements;
  • there is sustained or serious non-compliance with these terms or a condition of Approval;
  • there is deliberate or repeated misuse of the Seal or an Approval claim;
  • a serious safeguarding, safety, data protection or wellbeing concern is substantiated;
  • the Approval Holder fails to remedy a breach within a reasonable period specified by TDA; or
  • continued Approval would be materially misleading or would seriously damage the integrity of the CDWF.

10.5 Procedure

Except where urgent interim action is reasonably required, TDA will explain the concern, give the Approval Holder a reasonable opportunity to respond, and make a written decision. Suspension and revocation decisions are subject to TDA's Appeals and Complaints Policy.

10.6 Cessation and five-working-day grace period

On expiry without renewal, suspension or revocation, the Approval Holder must stop creating, approving or publishing any new use of the Seal or Approval claim immediately.

The Approval Holder then has five working days to remove or replace the Seal and Approval claims from live websites, digital listings, social profiles, current advertising, downloadable materials, and physical materials that remain under its control. It must confirm removal to TDA in writing if requested.

The Approval Holder must stop distributing new stock or materials bearing the Seal after the five-working-day period. Unless TDA directs otherwise because of a serious concern or misleading use, the Approval Holder is not required to recall packaging or materials that were lawfully distributed to third parties before the Approval ended.

10.7 Enforcement

Deliberate or repeated misuse after a request to stop, or continued use after the permitted removal period, may result in legal or other enforcement action to protect TDA's intellectual property and the integrity of the CDWF.

11. Fees

11.1 Fee schedule

Application, assessment, reassessment and renewal fees are set out in TDA's current Fee Schedule. Unless TDA agrees otherwise in writing, fees are payable by the applicant or Approval Holder.

11.2 Non-refundable fees

Application and assessment fees become non-refundable once substantive assessor review has commenced, except where TDA cancels the assessment or applicable law requires otherwise.

11.3 Changes to fees

TDA may review its fees annually. Changes will be notified at least three months before they take effect and will apply to new applications and renewals at the prevailing rate.

12. Confidentiality and assessment information

12.1 Confidential material

TDA will treat non-public application and assessment material as confidential and will use or disclose it only for assessment, quality assurance, governance, legal compliance, safeguarding, insurance, professional advice or other purposes described in TDA's Data Protection and Privacy Policy.

12.2 Scores and feedback

TDA will not publish detailed assessment scores or confidential feedback without the Approval Holder's consent, except where disclosure is required by law or is reasonably necessary to address a serious risk or correct a materially misleading claim.

12.3 Assessor information

The Approval Holder must not publish an assessor's identity, personal information or confidential assessment comments without TDA's prior written consent, unless disclosure is required by law.

13. Intellectual property

The Seal, the CDWF name, the assessment methodology and all associated intellectual property owned or licensed by TDA remain the property of TDA or the relevant rights holder.

The Approval Holder retains ownership of its own products, content, materials, names and other intellectual property. Nothing in these terms transfers ownership beyond the limited Seal licence in section 6.

14. Liability and indemnity

14.1 Basis of assessment

TDA's assessment is based on the information and evidence available at the time. The Approval Holder remains responsible for the Approved Subject, its legal compliance, its operation, its claims and its effects.

14.2 Excluded liability

To the fullest extent permitted by law, TDA is not liable for:

  • harm, loss or damage arising from the use, provision or conduct of an Approved Subject;
  • misuse of the Seal or an Approval claim by the Approval Holder or a third party;
  • a decision made by a customer, platform, funder, regulator, purchaser or other third party in reliance on Approval;
  • a change to the Approved Subject after assessment; or
  • indirect or consequential loss, loss of profit, loss of opportunity, loss of goodwill or loss of anticipated savings.

14.3 Liability cap

Subject to section 14.4, TDA's total aggregate liability to the Approval Holder arising from or in connection with an application, assessment, Approval or use of the Seal will not exceed the total fees paid to TDA for the relevant assessment.

14.4 Non-excludable liability

Nothing in these terms limits or excludes liability for fraud or fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot lawfully be limited or excluded.

14.5 Indemnity

The Approval Holder indemnifies TDA against reasonable claims, losses, liabilities and costs arising from the Approval Holder's misuse of the Seal, false or misleading representation of Approval status, material misrepresentation during assessment, or unauthorised use by a third party to whom the Approval Holder supplied the Seal.

15. Complaints, appeals and disputes

15.1 Complaints and appeals

Complaints and challenges to an assessment, suspension or revocation decision must first be raised through TDA's Appeals and Complaints Policy and within any timeframe stated in that policy.

15.2 Governing law

These terms and any non-contractual obligations arising from them are governed by the laws of England and Wales.

15.3 Mediation and courts

If a dispute is not resolved through TDA's internal process, the parties will attempt in good faith to resolve it through mediation before starting court proceedings, unless urgent injunctive or protective relief is required. The courts of England and Wales have exclusive jurisdiction.

16. Changes to these terms

TDA may update these terms from time to time. Approval Holders will receive at least 60 days' notice of a material change. Continued use of the Seal or continued representation of the Approved Subject as Approved after the notice period constitutes acceptance of the updated terms.

Where a change is required urgently to comply with law, protect children or address a serious integrity risk, TDA may introduce it on shorter notice and will explain the reason.

17. Acceptance

By submitting an application, accepting a decision notice, using the Seal, or representing a subject as CDWF Approved, the Approval Holder confirms that it has read, understood and agrees to comply with these terms.

Where an application is made on behalf of an organisation or team, the person accepting these terms confirms that they have authority to bind the Approval Holder.
