Policies

Rules for bothsides of the bid.

A marketplace is only as good as what runs on it. These policies say what advertisers may buy with us and what publishers may sell through us. They apply before the first bid.

Last updated: 7 October 2026

Advertiser policy

What may run,and what may not.

Advertisers are responsible for their ads, their landing pages and the data they send us. We review campaigns and may refuse or remove any that break these rules.

Prohibited content

Illegal products and services, malware and anything that tricks a device or its owner, deceptive or false claims, adult content, hate and harassment, weapons, and counterfeit goods. The same applies to similar content that the rules above plainly cover.

Restricted categories

Gambling, alcohol, financial products, health, dating and political advertising need review before they run. We may ask for licences, targeting limits or proof of eligibility, and some regions may be excluded.

Creative standards

The advertiser is clearly identified. Price and availability in dynamic ads match the product feed. Deep links open a working screen. No fake system dialogs and no misleading close buttons.

Audience rules

Audiences are built on consent.

Retargeting works on people who already used an advertiser's app, so the advertiser must be able to show that those people were told and, where the law requires it, agreed. The advertiser collects consent. We pass the signal along and respect it.

  • No sensitive audiences. No audience may be defined by health, sexual life, religion, ethnicity, political opinion or a similar sensitive category.
  • No children's data. Advertisers may not send data about children, or ask us to retarget users of a child-directed app.
  • Consent first. Without a valid advertising ID and the consent the law requires, a person is not addressed.

The data side is set out in the data processing addendum.

Only events that carry consent flow into an audience, and the rest are not used.

Publisher policy

What may be sold,and how.

Advertisers pay for real attention from real people. Publishers keep that promise by being open about what they sell and where.

Prohibited inventory

What we do not accept

  • Apps with illegal content
  • Pirated content
  • Made-for-advertising apps that have no real audience beyond the ad
  • Child-directed apps, which are excluded from retargeting
Required transparency

What every publisher shows

  • An app-ads.txt file that lists the sellers authorised to sell the app
  • Entries in sellers.json that match who is paid
  • Accurate bundle IDs on every request
  • A complete SupplyChain object that shows each party that handled the bid

Traffic and placement

Every impressionmust be real.

Invalid traffic
Prohibited. This includes incentivised clicks, hidden ads, ad stacking, auto-refresh abuse and spoofing of apps, devices or locations.
Placement
Ads must sit where a person can see and judge them. Layouts that invite accidental clicks, such as ads that shift under a thumb or sit on top of controls, are not allowed.
Privacy signals
Publishers pass consent and privacy signals accurately, including the person's tracking choice and any opt-out. A request that carries a false signal is treated as invalid.
Ownership
Publishers state truthfully who owns and operates each app, and keep that information current.

Enforcement

What happens when a rule is broken.

We look at ads before they run, we monitor traffic as it flows and we act on reports. Depending on how serious the breach is, we may ask for a fix, pause a campaign or an app, withhold or reverse payment for invalid traffic, or end the relationship. Where the law requires it, we tell the authorities.

To report an ad or an app, use the contact page. Tell us what you saw, where and when. Screenshots help.

Who decides if an ad is allowed?

We do. We apply these policies, and we may refuse a campaign even where the advertiser believes it is lawful.

Can a restricted category run at all?

Often, yes, once reviewed. We may set conditions on where, to whom and in what form it appears.

Why are child-directed apps excluded?

Retargeting depends on identifying a returning person from their behaviour. We do not do that to children, so those apps are left out of audiences and bidding.

What if my app-ads.txt is wrong?

Fix it and tell us. Requests that do not match your declared sellers may be blocked until it matches.

How do I report a problem ad?

Use the contact page and describe the ad and the app it appeared in.
