Selltics keeps a seller's Amazon advertising history indefinitely and deletes it only on that seller's written request, within thirty days of the request. The performance history is compressed once it is older than thirty days and is never expired or thinned, and the catalogue and configuration history is append-only, so superseded versions are kept alongside the current one. The raw event archive is grouped per advertiser and marketplace, and nothing expires a seller's records in it. Its performance part is grouped per advertiser account and profile: while an advertiser account has at least one activated profile, it holds every profile of that account, and the records of activated profiles are kept the same way. The records of the account's profiles that were never activated are the one exception: they are deleted seven days after the account's last activated profile is deleted, and that deletion is cancelled when a profile of the account is activated again before the seven days end. For that seven-day deletion, a profile that was activated at any time counts as activated, except one activated and deleted again before the collector first saw it activated and whose activation notice was also lost; its records are treated as never activated. Apart from that exception, disconnecting an advertising account or deleting a profile does not delete any of that history. A written request is recorded by Selltics against the profile it concerns, including a profile deleted earlier, and the profile is withdrawn from the product. A deletion job, tracked step by step, then removes that profile's rows from every advertising table of the time-series store, compressed history included, together with its ingest bookkeeping, and recalculates the daily summaries those rows fed. Once delivery for the profile has stopped, the job deletes the profile's part of the raw archive, in both its per-advertiser grouping and its per-account grouping, and repeats that a day later to catch deliveries that arrived late; the archive keeps no earlier versions of an object, so a deleted object leaves no copy in it. When the request removes the last activated profile of an advertiser account, a second job also deletes the archived records of that account's profiles that were never activated, and keeps those of every profile of the account the organization ever activated; the other activated profiles of the account keep their data. Never-activated profiles have no rows in the time-series store, so that job touches only the archive. A rebuild of the time-series store from the archive skips every profile with a deletion job, and after a restore from a database dump the deletions made since that dump was taken can be run again. Each job keeps a record of what it deleted and when, and a job still open seven days after its request is logged as overdue on every check, unless both of its archive passes have run without an error and it is only waiting for a temporary delivery copy to expire; as the register of absences states, nothing routes such a line to a person automatically. Four things are outside the job. Archive records that carry no advertiser or marketplace, and records the archive failed to deliver, mix every seller and cannot be deleted per seller; they expire after twenty-one days instead, and an hourly check logs any new one as an error. Copies already in the scheduled database dumps are not edited; they leave as the dumps rotate, after twenty-eight days for the time-series store, a window the backup control describes as a target rather than a guarantee. Raw records archived before the per-advertiser grouping existed sit in an earlier layout that mixes every seller and receives nothing new; Selltics is deleting that layout in full rather than sorting it, and a per-seller deletion does not reach whatever of it remains. The advertising figures the AI assistant was shown are not part of the job either; its run records are deleted thirty days after the conversation in any case.
