Why don't my monthly profile numbers add up to the total unique processed profiles?
This is expected. Monthly figures deduplicate shoppers within each month only, so the same shopper can be counted multiple times across different months. The billing total deduplicates across the full 36-month window, so each shopper is counted once.
Summing monthly values will almost always produce a higher number than your billing total — that's by design, not an error.
Can I use monthly data to estimate my quota usage?
No. Monthly reporting is useful for spotting trends, seasonality, and growth patterns — but it's not a reliable proxy for billing. Use the Total Unique Processed Profiles figure for anything quota-related.
What happens if I go over my quota?
Tracking continues without interruption. Overages are typically reviewed as part of contract discussions rather than triggering automatic blocks or data loss.
How long is data retained for billing purposes?
Profiles are evaluated on a rolling 36-month window. Only activity within the most recent 36 months is included in your billing total.
Are Behavioral Profiles tied to personal data?
No. Profiles are anonymised and do not contain personally identifiable information. The 36-month data window relates to aggregated behavioral signals used for AI processing — it is separate from any personal data storage obligations.
Why does the same shopper count multiple times in reporting charts?
Reporting charts show monthly unique profiles, which reset deduplication each calendar month. This is intentional — it lets you track engagement trends over time. It does not reflect how billing is calculated.
Does bot traffic count toward my Behavioral Profiles quota?
No. Bot filtering happens before a session is stored, so bot sessions are excluded before they can affect profile counts.
If a visitor browses two of my sites, do they count as one profile or two?
By default, they are treated as two separate visitors with two separate profiles. If you have Enhanced Shopper Identification enabled, Nosto can link activity across sites and count them as a single profile.
If the same visitor browses on multiple devices, do they count as one profile or two?
It depends on whether Nosto can identify them. Unidentified visitors on different devices are treated as separate profiles. If a visitor is identified — for example, by logging in — Nosto consolidates their cross-device activity into a single Behavioral Profile.
