How long is location history kept?
Location history is kept for a limited period, not forever. Retention is not configurable by the organisation yet, and the team is working on that. If your policy needs a specific period, ask Skie support and have the answer written into your agreement rather than relying on assumption.
Skie records location so that an administrator can see where a device is and, in lost mode, build a trail for a police report. Location history is not kept indefinitely. The exact period is not something this knowledge base states, because the honest answer is that it should be written into your agreement.
Configurable retention, where an organisation picks its own period, is not available yet. The team is working on it, with no date to give. Until then, the period is set by Skie, and you can ask what it is.
This matters for your own notice. If you tell parents how long location is kept, the statement must be accurate. Ask Skie for the current period in writing, record it in the privacy notice and review it when you renew the agreement.
You can also reduce the amount of location data in the first place. Use location for lost devices only, or only for particular groups, and restrict the pages with page access by role. Less visibility inside the organisation means fewer people handling the data.
A practical tip: keep a short note in your data record with the retention period, the date you were told and who told you. If a parent asks how long their child's location history lasts, you can answer in one sentence and cite the source.
