Cross-tenant data handling disclosure

Last updated: 2026-07-19

What cross-fleet intelligence is

Denpex pools anonymized, aggregated failure signatures across customer fleets, so a failure class seen in one fleet can warn others before it reaches them. This page discloses exactly what leaves your fleet for that pool, what never does, and the controls you have over it.

Exactly what is shared

Only these four fields are ever contributed to the pool:

  • The failure class identifier.
  • A one-way FNV-1a signature hash computed over failure type + GPU-count bucket + Xid code + driver major version.
  • A timestamp coarsened to the hour.
  • Aggregate counts of how many times the signature was observed.

What is never shared

  • Raw log lines.
  • Hostnames.
  • IP addresses.
  • Tenant names or tenant IDs.
  • Job names.
  • User identities.
  • Timestamps finer than one hour.
  • Exact GPU counts (bucketed only).
  • Any free-text field.

A signature is only ever revealed when at least 5 distinct tenants have contributed to it (k-anonymity floor, k = 5). Below that floor, the pool returns nothing.

How anonymization is enforced

  • Signatures are constructed from a field allowlist, not a denylist: the aggregator copies only the enumerated fields above, and everything else is dropped before hashing.
  • Tenant identifiers are never written to the pool.
  • Aggregation happens in a separate Durable Object with its own storage, isolated from per-tenant data.

Your controls

  • Data Center customers may opt out of contributing signatures; your fleet still receives cross-fleet warnings.
  • Cross-fleet intelligence is unavailable on the Free plan.
  • You can request deletion of your contributions by contacting privacy@denpex.com. Contributions are anonymous and cannot be re-associated with your account, so deletion applies to future contribution windows.

Legal basis & review

This disclosure is reviewed each quarter. Material changes are announced 30 days before taking effect, on this page and by email to account owners.
