The design in one paragraph

Conversations are processed transiently to generate a reply and are not intentionally retained by us afterward. Your history is stored only as encrypted data under a key you hold; we cannot read it. This posture is internally tested, not independently audited. Our testing covers the surfaces we have enumerated, not every conceivable one.

What we hold and for how long

Data classWhat it isRetention
Encrypted envelopesYour history and saved context, encrypted client-side. We hold ciphertext only.Until you delete it or close your account
Sync metadataTimestamps, sizes, and version markers needed to sync envelopes between your devicesUntil the related envelope is deleted
Account identifiersEmail or login handle, hashed credentialsLife of the account
EntitlementsWhich plan you are on, renewal dates, credit balance, payment status (not card numbers)Life of the account, then per the retention table
Security eventsLogin failures, abuse signals, enforcement actions90 days
Anti-abuse countersTransient rate and pattern countersUp to 24 hours
Infrastructure logsServer and network logs without conversation content30 days
AggregatesCounts and totals with no per-user linkage13 months

Some business, tax, and payment records must be kept for the periods the law sets; the retention table for those is being confirmed with counsel and will be published here.

What we do not hold

Plaintext conversation content after inference (see posture above). Card numbers: our payment processor holds them, not us.

Processors

We use a small number of service providers to run the Service: [PROCESSOR LIST] (payments, hosting/inference). Each is bound by contract to use data only to provide the service to us. We publish the list and update it when it changes.

No sale, no ads

We do not sell or share personal information for money or for advertising. We do not run third-party trackers or advertising scripts on our sites or apps. We do not use your conversations to train models.

Your rights

Wherever you live, you can: see what we hold about your account, correct it, export it, and delete it. Deleting your account removes the data classes above, except what the law requires us to keep. California residents have the additional rights described in the CCPA/CPRA, including the right to know, delete, correct, and not be discriminated against for exercising them; we do not sell or share personal information, so there is nothing to opt out of. To make a request, use Settings → Privacy or email hello@dusken.chat. We verify requests through your account and answer within the time the law sets (45 days in California).

Security

Data in transit is encrypted. Your history is encrypted on your device before it leaves it. Our security controls are internally tested, not independently audited; we will say so plainly until that changes.

Legal requests

We comply with valid legal process. We can only produce what we hold, in the form we hold it (see the table). We notify affected users when the law allows.

Children

The Service is for adults in professional practice. We do not knowingly collect information from anyone under 18; if we learn we have, we delete it. Material changes to this notice are posted with an effective date before they take effect.
