Security and data handling

How we handle your data.

Updated October 28, 2026

Everything a firm's privacy counsel or security reviewer asks us, on one page. The documents that govern are the Privacy Policy, the Terms of Service and the Subprocessor list; this page summarizes them and never overrides them.

Two promises

Zero-retention AI. Your work kept until you delete it.

Two things are true at once, and we state them separately because they are often confused. No AI provider retains or trains on your content; that has never changed. And we keep your documents and work product until you delete them: they are never deleted on a schedule, and there is no timer to turn on. Only temporary copies we make to deliver or process them expire.

Where your data lives, and who touches it

Encryption and keys

Custody, deletion and backups

No deletion clock

Data stays until the firm deletes it. Nothing is deleted on a schedule, and there is no setting that does.

Delete means delete

Deleting a document, a project, a matter or an account removes the record, the search index and the file from live systems in the same operation. There is no trash can and no restore.

Backups age out in 30 days

Encrypted nightly backups exist for whole-system recovery only. Deleted data leaves them within thirty days. We never restore individual items from backup.

Restores are tested

We perform periodic tested restore drills to confirm that backups can actually be recovered.

Deletion with a certificate

A deletion can be documented: an inventory of what was removed, gone from live systems at once and from backups on the published schedule.

Archive with a button

Close a matter to the archive rate and bring it back yourself. Archiving changes the rate, not the custody.

Because deletion is permanent, keep your own copy of anything you cannot afford to lose. That is prudent practice, not a limit on our obligation to hold what you have entrusted to us.

Preservation holds

Your firm can place a preservation hold on a matter, with the reason recorded. While it is on, nothing under that matter can be deleted, by a user or by us: every delete path asks the hold first and refuses out loud. Setting and releasing a hold are both written to the audit log, so preservation can be demonstrated after the fact. Deciding whether a hold is required, its scope and its release remains the attorney's judgment and the firm's duty; we provide the mechanism.

Tenant isolation and access

When an agreement ends

Cancelling a subscription deletes nothing, and does not by itself end your firm's agreement with ArsLex. When the agreement does end, your firm has thirty days to export its data or to have us provide it. After that export period we delete the firm's content, served productions and held matters included unless a legal demand directed at ArsLex requires us to keep it, and the deletion is carried out deliberately by ArsLex personnel, never by a scheduled job.

Compliance posture

Security reviews and questionnaires

Our Information Security Addendum (Schedule B to the Master Services Agreement) describes the controls behind this page in contractual detail: hosting, encryption, access control, logging, personnel, secure development, incident response, backups and recovery, vendor management and independent assessment. It is provided to customers and to prospects under NDA, together with the Data Processing Addendum, on request to legal@arslex.ai. Send security questionnaires to the same address.
