Key Takeaways

  • Log retention for phone-as-gateway stacks: decide TTL for API history, app logs, and the handset SMS database — they are three stores.
  • OTP plaintext should not live in long support dumps.
  • Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Retention policy is separate from plan metering.
  • Free 300 SMS lifetime still creates records — purge demos.
  • Align with privacy/security pages; counsel for your jurisdiction.
  • Minimize PII in webhook payloads you persist.

Verify against your store, not against immortal logs — OTP.

On-device SMS history

Include handset wipe / shared-device rules in ops runbooks. Lost phones are data events.

Support exports

Prefer IDs and timestamps over full bodies. Staff access least-privilege. Pair with wording hygiene.
