Piano Analytics Mobile SDKs

Coming Soon

Our iOS and Android SDKs are coming soon

Legacy cookie management

If you're migrating from SmartTag SDKs to Piano Analytics SDKs, we still use the atuserid cookie (visitor identification) so as not to cause a break in the detection of the visitor. As soon as this atuserid cookie is deleted, we replace it with pa_vid cookie.

The atauthority cookie (Privacy) is not used anymore. Please implement Privacy methods to deposit the new pa_privacy cookie instead.

Same applies for legacy atidvisitor cookie ("identified visitor" detection, now "user"). Please implement Users methods to deposit the new pa_uid cookie instead.
