the.com/safekeeping

The promise that nothing bad will happen, filed somewhere you'll later forget.

means The state of being protected and looked after so nothing is lost, stolen, or damaged — or the custody someone holds it in for that purpose.

from A straightforward compound from Middle English: 'safe' (secure, from Old French sauf, ultimately Latin salvus) plus 'keeping' (from Old English cepan, to hold onto, guard, pay heed to). No hidden plot twist here — it means exactly what it looks like, and has since at least the 1400s, when people started wanting a word for handing something over without losing sleep over it.
