Abstract illustration: data retention and trust
Trust + privacy

A simple data retention policy for small online tools (that users can trust)

Users don’t need perfect privacy marketing — they need clear defaults and predictable behavior. A simple retention policy is often better than a vague “we respect your privacy.”

In practice, retention is about reducing blast radius. The less you store, the less you can leak. For many verification-style tools, you can design the system so user inputs are processed and discarded, while operational logs remain minimal and time-bounded.

A conservative baseline

  • Don’t store user-submitted content by default.
  • Keep security/availability logs, but minimize payload and duration.
  • Separate operational logs from any content storage (different systems, different controls).
  • Document exceptions (e.g., abuse prevention, legal obligations) plainly.

A simple template you can adopt

  • Inputs: processed to compute results; not stored by default.
  • Operational logs: limited fields (timestamp, request id, status, latency); retained for a short window.
  • Abuse prevention: limited metadata to rate-limit and prevent denial-of-service.
  • Support: user-submitted tickets may include content you choose to provide; retained as long as needed to resolve the issue.
The trust win: make the “default” easy to understand

If users can’t tell what happens to their input, they assume the worst. A short retention statement in your product UI (not only a legal page) reduces uncertainty and increases adoption.

Policy clarity checklist
  • States whether inputs are stored by default.
  • States log retention duration.
  • Explains third-party processors (if any).
  • Explains how to request deletion or contact support.

How to keep policies aligned with reality

A retention policy only builds trust if it matches system behavior. Operationally, that means making storage explicit: what gets stored, where, for how long, and how it’s deleted. If you cannot confidently answer those questions, tighten defaults and simplify the architecture.
