When you search the logs for "Cleaner", does anything turn up at all?

Also, check for "MapDataController", the deletion of old data emits the following log message: "Deleted old elements and geometries"

Subsequently, the "OsmQuestController" should emit a log message like "Persisted 0 new and removed already resolved quests in s".

Using maunal upload, if it matters.

It now deleted the most old quests/data however some randomly placed are still there.

I see this message, not sure about the ordering.

Looking more closely on the quest, I can not find POI/amenity quests they are almost all related highways. No standalone nodes. Quests only show up on node that are part of a way or on ways. In both cases the way is part of a relation.

(Observations from a sample)

[westnordost]

But what does it say? How many old elements deleted? Were quests deleted? Does the time of these log messages coincide with the cleaner running?

Okay, let's dissect this.

2026-03-12T15:46:42.771: I [Cleaner] Cleaning took 2999.7s
2026-03-12T15:46:43.095: I [Cleaner] Cleaning took 2996.8s

Two cleaner jobs that took a perplexing amount of time finished within the same second. Both took very close to 50 minutes, a suspiciously round time. Did it run into some kind of timeout? I note that this log happened after you posted this issue report, though.

Are there any error logs in-between 2026-03-12T15:46:43.095 and 50 minutes before?

On why two cleaner jobs apparently run in parallel: The cleaner is exclusively started by a background job we tell the Android system to run daily (at any time, in the background). However,

Did you press on "Delete cache" in the settings screen on the 12th?

2026-03-11T08:27:37.892: I [MapDataController] Deleted 100000 old elements and 35327 geometries
2026-03-12T15:46:42.118: I [MapDataController] Deleted 100000 old elements and 0 geometries

Wow, you have been downloading a lot of data. This round number looks suspect, and indeed, it is a limit set by StreetComplete because until 5 years ago, I got rare crash reports about out of memory errors from creating the SQL statement string to remove all those ids (e.g. DELETE FROM osm_nodes WHERE id in (<a list of 100000 ids>)). So, the fix was to just limit the amount of maximum elements deleted in one go.
This seems to what have happened here. So, a few quests remained. Did this lead to any actual issue? After all, one day later, i.e. 15 days after, that old data was completely removed it seems.

That's all logs I have. Device update/reboot.

Did you press on "Delete cache" in the settings screen on the 12th?

No

Wow, you have been downloading a lot of data.

I map offline and having around 150km² of data downloaded in SC worked quite well for me in the last two years. 100km² of the being downloaded at the same time and deleted at the same time is normal too.

Did this lead to any actual issue?

Only cosmetic issues (quests/data and diagonal bars).

[westnordost]

As for why the cleaner took so much time on the 12th, except that it seems there wasn't an internet connection then, there were no errors or anything. So at the moment I'll just assume that Android froze the background job for 50 minutes and then continued later. 🤷 It can't be the source of the issue you reported anyway, because that happened after you reported this issue.

Only cosmetic issues (quests/data and diagonal bars).

I see, okay.
