“Deletes audio after transcription” can mean two very different things. Some cloud services delete their copy of your recording from their servers after processing, or when you ask. You have to trust that they do. On-device apps can delete the recording from your own phone as soon as the text is ready, and no server copy ever existed. The safest combination is an app that transcribes on the device and deletes the audio automatically, leaving only the text. Private Transcribe does that when you switch off “Keep recordings.” Among cloud tools, check each service’s policy, because retention varies a lot.
Server deletion vs local deletion #
| Server deletion (cloud apps) | Local deletion (on-device apps) | |
|---|---|---|
| Was the audio uploaded? | Yes | No |
| Who deletes it | The provider, per its policy or your request | The app, on your phone |
| Can you verify it? | Only through the provider’s word and audits | Yes, the file is gone from your device |
| Backups and logs | May persist for a period, per the policy | Only what you back up yourself |
| Risk before deletion | Breach, legal request, human review, training | Losing an unlocked phone |
Server deletion is still worth having. A service that wipes files promptly holds less data to lose. But it reduces risk after the fact, while local processing avoids it.
How popular apps handle your audio #
| App | Where it transcribes | What happens to the audio |
|---|---|---|
| Private Transcribe | On your phone | Kept for playback by default; deleted automatically after transcription if “Keep recordings” is off |
| Live Transcribe (Android) | On the phone in offline mode | Transcriptions kept up to 3 days, or 24 hours with history off |
| Speechnotes | Browser or OS engine for dictation; online for file transcription | Says transcription files are deleted automatically after processing |
| Sonix | Cloud | Kept in your account; audio and transcripts wiped when you delete them |
| Wispr Flow | Cloud | A “Dictation Cloud Storage” setting controls whether audio and transcripts are stored |
Policies change, so read the current terms of any cloud service before trusting it with sensitive recordings.
How automatic deletion works in Private Transcribe #
Private Transcribe runs OpenAI’s Whisper on your iPhone or Android phone. There’s no account and no transcription server, so deletion happens only on your phone, and it’s complete when it happens.
- Keep recordings off: go to Settings and turn off Keep recordings. From then on, each recording is deleted the moment its transcript is saved. You keep the text, timestamps and word count, but not the audio.
- No speech, no leftovers: if a recording turns out to contain no speech, the app deletes it rather than keeping an empty entry.
- Imports: when you import a voice memo or video, the app decodes a working copy to transcribe. Your original file in Files or Photos is never copied into the app or changed, so delete the original yourself if you want it gone.
- Delete individual transcripts from History, or use Settings > Clear All Data to remove every recording, transcript and downloaded model at once.
- Uninstalling the app removes everything too. There’s no server copy to request deletion of.
The trade-off: without the audio you can’t replay a sentence to check a word. If that matters, keep recordings on until you’ve reviewed the transcript, then delete them from History.
Don’t forget the other copies #
Deleting the audio in one app doesn’t delete it everywhere. Check these:
- The original recording. A voice memo you imported still sits in Voice Memos or your recorder app.
- “Recently deleted” folders. Many recorder and file apps keep deleted items for a while before removing them for good.
- Cloud sync and backups. Voice Memos, Notes and file folders may sync to iCloud or Google. Backups can include files you’ve since deleted on the phone.
- Shared copies. Anything you sent by email or messaging exists on the recipient’s side and the service’s servers.
What to check in a cloud service’s deletion policy #
If you use a cloud tool, look for clear answers to these:
- When is audio deleted? Immediately after processing, after a set number of days, or only when you delete it?
- What about backups? Deleted files often remain in backups for a period.
- Is anything used before deletion? Human review, quality checks or model training.
- Which subprocessors receive the audio, and what are their retention rules?
- Can you delete everything yourself, including the transcript, from the app?
Should you delete the audio at all? #
For most voice notes, yes, once you’ve skimmed the transcript. Text is small, searchable and easy to secure, while audio holds your voice, background conversations and details you didn’t mean to record. For interviews, meetings and anything you might quote, keep the recording until you’ve checked the important parts, then delete it according to your own retention needs.
For recordings with health or legal information, retention may be governed by rules at work. See private transcription for healthcare compliance for the healthcare angle. For the bigger privacy picture, see on-device vs cloud transcription. The iPhone routine, including how to import and then clean up voice memos, is in private voice notes to text for iPhone. Other local-only tools are compared in speech-to-text apps that work completely offline.
Frequently asked questions #
Do transcription apps keep my recordings? #
Most cloud transcription apps keep your audio in your account until you delete it, because a searchable archive is part of the service. On-device apps keep recordings only on your phone, and some, like Private Transcribe, can delete each one automatically after transcribing.
Can a cloud service recover audio after I delete it? #
It depends on the provider. Deleted files may remain in backups for a period before they’re purged. If that matters, ask the provider for its backup retention period, or use an on-device app so there’s no server copy in the first place.
Does deleting a transcription app delete my recordings? #
For on-device apps that store everything locally, uninstalling removes the app’s recordings and transcripts. Private Transcribe works this way. For cloud apps, deleting the app from your phone doesn’t delete anything on the provider’s servers. You need to delete your files or account there.
Should I keep the audio to check accuracy? #
Keep it until you’ve reviewed anything you’ll quote or act on, especially names and numbers. After that, the transcript is usually all you need. Timestamps make the review quick while the audio is still there.
How do I delete a voice memo after transcribing it? #
Delete it in the app where it was recorded, such as Voice Memos. Then empty that app’s recently deleted folder if it has one, and make sure it isn’t kept in a cloud backup you don’t want.
