What Happens to Advertiser Data When an Advertiser is Deleted

NinjaCat customers often manage a large roster of advertisers, and that roster naturally changes over time. Advertisers come and go, and some are removed once an engagement ends. This guide explains what you can expect to see in the platform when an advertiser is deleted, so you can manage your account confidently and know your reporting will reflect the right view of your business.

Quick summary

NinjaCat advertisers have two states:

There is no separate "inactive" state for advertisers in NinjaCat. An advertiser is either Active or Deleted. Deleting an advertiser is a soft action — the record is hidden from normal views but can be restored by NinjaCat Support if needed.

Active advertisers

Active advertisers are the default. NinjaCat regularly refreshes data for them from your connected platforms, and they appear in your reports, dashboards, and exports as normal. There's nothing to configure — this is the standard behavior.

Deleted advertisers

Deleting an advertiser tells NinjaCat that the advertiser should be excluded from your reporting going forward. It's a soft-delete: the advertiser is hidden from normal views, but the record itself is recoverable by NinjaCat Support.

What you'll see on the dataset side (datasets, dataset-powered reports, and dashboards built on datasets):

• The advertiser is filtered out of all reporting outputs. Reports, dashboards, and dataset exports will no longer include them.
• This applies to both new and historical reporting — once deleted, the advertiser's data stops appearing in dataset outputs entirely.

What you'll see on the legacy data warehouse (RDW) side (older reports built on the legacy data warehouse rather than datasets):

• Legacy data warehouse reports follow standard data retention policies for each data source rather than reacting to advertiser deletion. In practice, that means historical data on the legacy side ages out on its normal schedule.
• If you're working primarily on the dataset side (the modern NinjaCat reporting experience), the dataset-side behavior above is what governs what your end users see.

Not sure which side you're on? Most modern NinjaCat reports and dashboards are built on datasets. If you're building reports in the dataset-powered experience, the "dataset side" rules apply. Your NinjaCat representative can confirm if you have any legacy reports still in use.

A note on data privacy and removal

Deleting an advertiser ensures their data is no longer surfaced in your NinjaCat reporting. If you have a specific data removal need that goes beyond hiding an advertiser from reports — for example, a data subject request or contractual data removal — please contact NinjaCat Support so we can help you handle it appropriately.

Restoring a deleted advertiser

If an advertiser is deleted by mistake, contact NinjaCat Support. In many cases we can restore the advertiser, after which:

• The advertiser becomes visible in your active advertiser list again.
• New data refreshes resume on the regular schedule for their connected data sources.
• Historical data that was already in NinjaCat before deletion remains available — there's no re-import needed.

Frequently asked questions

Will my monthly report match the sum of my daily reports if advertisers are deleted during the month?

If you deliver scheduled reports (for example, a daily CSV to an SFTP destination plus a monthly summary), it's worth understanding how advertiser deletions interact with those exports.

Each report reflects the current state of your advertiser roster at the moment it runs. If an advertiser is deleted partway through the period, a daily report delivered before the deletion will have included that advertiser, but a monthly report run after the deletion will exclude them. As a result, the monthly total may be lower than the simple union of the daily files for that period.

What this means in practice: Files already delivered to your SFTP destination are not modified retroactively — once a daily CSV is written, it stays as-is. The discrepancy comes from the monthly report being generated after the deletion, against a roster that no longer includes the removed advertiser.

If matching daily and monthly totals is important for your downstream process, we recommend timing advertiser deletions to period boundaries (for example, deleting at the start of a new month rather than mid-month). If you need help structuring this for a specific reporting workflow, reach out to NinjaCat Support.

Will deleting an advertiser remove old reports that already include them?
Reports already exported or shared outside of NinjaCat (for example, PDFs or CSVs you've sent to clients) are unaffected — those copies live wherever you saved them. Inside NinjaCat, dataset-powered reports and dashboards will no longer include the deleted advertiser the next time they refresh.

Can I get a deleted advertiser back?
Yes, in most cases. If you delete an advertiser by mistake, contact NinjaCat Support as soon as possible and we can help restore it.

Is there an "inactive" status for advertisers?
No. Advertisers in NinjaCat are either Active or Deleted. There is no separate inactive or paused state at the advertiser level.

Does this apply to my data connections too?
This guide covers advertiser-level deletion. Data connections (the platforms you've authorized NinjaCat to pull from) are managed separately. See How Historical Data Syncing Works in NinjaCat for related context.
