A voice-recording retention policy turns “we delete recordings eventually” into a controlled process. It should identify every copy created by the workflow—including audio on the recorder, synced app files, transcripts, summaries, exports, email attachments and backups—and state who deletes each copy, when deletion is triggered and how exceptions are approved.
Quick verdict: Do not choose one blanket retention period for every recording. Set a justified schedule for each purpose, keep raw audio only while it is genuinely needed and verify that deletion reaches device, app, export and backup copies.
This guide provides general information, not legal advice. Organisations should align the policy with current UK GDPR requirements, sector rules, contractual duties, safeguarding obligations and their own records-management schedule.
What the policy must answer
- Which recording activities are approved?
- Why is each record retained?
- What event starts the retention clock?
- Who owns deletion and exceptions?
- How is deletion proved?
Map every record created
| Record class | Typical location | Main risk |
|---|---|---|
| Original audio | Recorder, phone or app | Contains more information than the final note |
| AI transcript | Transcription service or export folder | Errors may be treated as fact |
| Approved summary | Official business system | May omit disputed context |
| Exports and shares | Email, cloud drives and messaging tools | Copies escape the controlled workflow |
| Backups and logs | Supplier or corporate infrastructure | Deletion may be delayed or indirect |
Use purpose-based, event-triggered schedules
Retention should be linked to a defined business event. “Delete 30 days after approved minutes are issued” is operational; “keep for a short time” is not.
- Routine internal meeting: delete raw audio after minutes are approved and the correction window closes.
- Customer call: apply the documented complaint, quality-monitoring or transaction schedule.
- Research interview: follow the ethics-approved destruction date and permitted de-identification plan.
- HR investigation: follow the employment-record schedule and any active dispute or legal-hold process.
- Safeguarding or incident record: use the relevant specialist policy rather than a routine meeting schedule.
The transcript, approved note and raw audio may need different periods. Keeping a final note does not automatically justify retaining the source recording for the same length of time.
Retention schedule template
| Use case and purpose | The specific approved activity and why the record is needed |
| Record classes | Audio, transcript, summary, exports and metadata |
| Trigger and period | The event starting the clock and justified duration |
| Owner | The role accountable for deletion |
| Exception route | Who can place or remove a legal, safeguarding or investigation hold |
| Evidence | Deletion report, log, sample audit or signed review |
Control exceptions
A legal hold, active complaint, investigation, insurance claim or safeguarding requirement may suspend routine deletion. Record the reason, records covered, approving role, review date, release trigger and deletion action after release. “Keep just in case” is not a controlled exception.
Delete across the whole lifecycle
- Remove the file from the recording device.
- Remove synced audio and text from the app or transcription account.
- Delete local downloads and duplicate exports.
- Remove copies from shared drives, email and messaging tools.
- Understand supplier backup handling and delayed deletion.
- Retain only the authorised final record in the official system.
Using NERALVO Halo within the policy
NERALVO Halo is an ultra-slim AI voice recorder with 64GB local storage, up to 35 hours of recording, NOTE and supported CALL modes, Bluetooth synchronisation with the DOWAY app, and AI transcription, summaries, templates, translation, mind maps and exports. One year of DOWAY Max access is included.
The policy should identify when local audio is removed from Halo, when synced content is removed from DOWAY, where approved exports are stored and who checks that uncontrolled copies have not been retained. Recording must always be lawful, disclosed where required and permitted by the relevant organisation and platform.
Make the policy operational
- Give every approved use case a named owner.
- Build deletion dates into case or project systems.
- Restrict exports where possible.
- Train staff not to keep personal backup copies.
- Review supplier deletion terms and technical options.
- Audit a sample of recordings and exports periodically.
- Review the policy after changes to suppliers, AI features, law or purpose.
Frequently asked questions
Should every recording use the same period?
No. A routine meeting, complaint call, clinical discussion and research interview have different purposes, risks and sector requirements.
Can raw audio be deleted once the transcript exists?
Often, but only after the transcript or approved note has been checked and any necessary correction or dispute period has ended.
Does deleting from the app remove every copy?
Not necessarily. Check device storage, exports, shared folders, attachments, supplier backups and linked systems.
Final checklist
- Every record class is listed.
- Every period has a documented purpose and trigger.
- Every deletion action has an owner.
- Exceptions are time-limited and reviewed.
- Device, app, export and backup copies are addressed.
- Deletion is tested and evidenced.
A strong retention policy creates a repeatable route from lawful capture to checked output, controlled storage and provable deletion.
