Storage & retention
Every run you start is saved with its logs, metrics, and output files so you can come back to it later. To keep things fast and costs predictable, older runs are cleared on a rolling schedule.
How long runs are kept#
Completed runs are retained for 30 days. After that, a run's stored artifacts — its logs, GDS, and other generated files — are automatically removed. This happens on a daily cleanup pass, so a run drops off roughly a month after it finished.
Keep anything you need long-term
If a particular layout or result matters to you, download it from the analysis workspace or viewers before it ages out. Run outputs are easy to re-generate by running the design again, but the stored copy isn't kept indefinitely.What is and isn't removed#
- Removed after 30 days:a run's generated artifacts and its entry in run history.
- Always kept: your projects and their source files — retention only applies to run outputs, never to the design you wrote.
- Always kept:your usage history. The compute minutes and AI credits a run consumed stay on your account ledger even after the run's files are cleared.
In-progress runs are never touched by cleanup — only finished runs past the retention window are eligible.
How storage is measured#
Storage is the total size of the files held on your account: your project sources plus the artifacts of runs still inside the retention window. Because old runs age out automatically, your footprint stays bounded rather than growing forever.
Higher plans come with more generous limits. See Plans & usage for what your tier includes, and Run history for how to revisit past builds while they're available.
