How do IP truncation and data retention work?

What truncation, stripping and retention each do, and how your plan caps the retention period.

Short answer

Address truncation drops bytes before the geo lookup (the country is always kept). Stripping replaces email- and phone-like strings in properties. Retention defaults to 12 months for events but is capped by your plan: 6 on Free, 12 on Pro, 24 or more on VIP.

Truncation and stripping

  • Address truncation — off by default. IPv4 can drop its last 1 or 2 bytes before the geo lookup, and IPv6 can be cut to a /64, /56 or /48 prefix, optionally for some regions only. The CNIL exemption preset forces at least 2 bytes for IPv4 and /64 for IPv6. The country is always taken from the full address; truncation only affects region / city precision, and the address itself is never written to the event.
  • Stripping — when enabled, strings that look like an email or phone number in event properties are replaced with a placeholder. Autocapture does not capture visible text by default.

Retention is capped by your plan

Defaults inside the compliance config are 12 months for events, 90 days for autocapture, and 24 months for profiles and consent receipts. The effective value is capped by your plan: 6 months on Free, 12 on Pro, 24 or more on VIP. A scheduled job deletes expired rows. Two presets — pseudonymous statistics without consent, and identified collection with full consent — set several fields at once and lock them until released.

Retention changes apply going forward and to existing rows: lowering it deletes older rows on the next scheduled run. Export first if you need them — see export and deletion.
