What Limn stores
Where Limn keeps its data, what it keeps, for how long, and how to move or delete it.
Everything Limn keeps is on your computer, in one folder: ~/.limn (the .limn folder in your home folder). Nothing is kept anywhere else by Limn. This page says what is in the folder, how long Limn keeps it, and how to move it.
#The ~/.limn folder
| What | Why |
|---|---|
| The database | Synced pull request activity, your settings, AI results |
| Repository copies | The code AI runs and the conflict resolver read |
| The AI programs | Claude and Codex, downloaded on first start |
| Limn’s Codex sign-in | Kept apart from your own Codex setup |
| The scoring model | Bot comment scoring, if you set it up |
Sandboxes for AI Fix and Implement live in your container runtime, not in this folder. Remove leftovers with limn sandbox prune.
#What is in the database
- From GitHub: the repositories you added, their pull requests, reviews, comments (with their text), review threads, commits, check results and events. Some detail, such as a pull request’s description and full CI results, is fetched again when you open it rather than stored.
- From your trackers: the tickets your pull requests link to, once a tracker is set up.
- From you: your workspaces, settings, dismissals and the Docs library you add.
- From the AI: each review, fix, plan, chat and summary, with the provider and model that ran it and what it used.
Tokens you give Limn
Tokens for Jira, Linear, Notion, Confluence and SonarCloud, and the Slack webhook, are stored sealed (encrypted) in the database. The app never shows them again and never includes them in an export. Your GitHub sign-in and your Claude or Codex credentials are not in the database at all.
#How long Limn keeps it
A first sync reads about 90 days of history. Once a day, Limn removes every pull request that has had no activity for 180 days, with everything attached to it. Repository copies left by finished AI runs are removed when Limn starts and when a new run begins; an unpushed fix is kept for up to 14 days.
#Move the folder
- Start Limn with
LIMN_DATA_DIRset to another folder to keep everything there. - Start Limn with
--dband a file path to use a different database file. - If you used Limn under its earlier name, an existing
~/.pierre-reviewfolder is moved to~/.limnonce, on first start. An existing~/.limnis never overwritten.
The settings that never leave this browser, such as the Colour scheme, are kept by the browser, not in the folder.
