Indefinite retention
You are agreeing to indefinite data retention based on Meta's subjective assessment of necessity.
“We keep information as long as we need it to provide our Products, comply with legal obligations or protect our or other’s interests. We decide how long we need information on a case-by-case basis.”
What that means: Your data may never be fully deleted if Meta deems it useful for future business operations.
The company decides retention time individually based on vague criteria like "legitimate purposes" rather than fixed periods.
