The short answer
Whizi does not use your prompts, files, conversations, voice transcripts, or generated content to train Whizi-owned AI models. Whizi does not sell that content as training data.
Uploaded attachments and generated media are configured to expire after up to 30 days. You can delete them sooner, and account deletion removes them along with the rest of your data.
What happens when you send a message
Whizi is a workspace in front of models built by other companies, so a message you send to Claude reaches Anthropic, and a message you send to GPT reaches OpenAI. That is what selecting a model means, and no aggregator can change it.
The practical implication is that the provider whose model you selected handles that request under their own terms. If a particular provider is unacceptable for a class of work, the answer is not to trust a wrapper, it is to not route that work to that model. A multi-model workspace makes that easy in a way a single-vendor subscription does not, because you can move sensitive work to a different provider without changing tools.
Nothing is sent to a model you did not select. Switching models mid-conversation sends the existing thread to the newly selected model, which is what makes continuity work and is worth knowing before you switch on a sensitive thread.
Retention
| Data | How long |
|---|---|
| Uploaded attachments | Configured to expire after up to 30 days |
| Generated media | Configured to expire after up to 30 days |
| Conversations and messages | Kept until you delete them or delete the account |
| Saved memory | Kept until deleted |
| Entitlement and usage state | Kept while the account exists |
You can delete particular content without deleting the account, so removing one conversation or one uploaded file does not require the nuclear option.
The local chat cache on a device is separate from the server-side record. On mobile it can also be removed by clearing app storage or uninstalling the app, which is worth knowing if you are handing a device on.
Account deletion
Deletion is available at whizi.io/account-deletion and can be started from the app as well. It removes your conversations and messages, uploaded and generated media, saved memory, entitlement and usage state, guest identity links, push tokens, the Clerk authentication account, and the local data on the device completing the deletion.
A limited retention window applies to the records that have to survive briefly for legal and operational reasons. That is described in the privacy policy rather than summarised here, because the specifics are what matter.
One thing deletion does not do: stop an App Store or Google Play subscription. Those bill until cancelled with the store that sold them, independently of whether the Whizi account still exists. See billing and cancellation.
What to think about before uploading work documents
Two habits worth having, neither specific to Whizi.
First, remember that extracted document text becomes part of the conversation. If you later share that conversation as a link, the extracted text goes with it. Check a thread before sharing it, particularly a long one that changed subject partway through. See sharing a conversation.
Second, know your own organisation policy on which providers are approved. The useful property of a multi-model workspace here is that you are choosing per message rather than per subscription, so an approved-provider rule is something you can actually follow rather than something you have to work around.

Frequently asked questions
Does Whizi train AI models on my conversations?
No. Whizi does not use your prompts, files, conversations, voice transcripts or generated content to train Whizi-owned AI models, and does not sell that content as training data. Uploaded attachments and generated media are additionally configured to expire after up to 30 days rather than being retained indefinitely.
Where does my message actually go?
To the provider of whichever model you selected, because Whizi is a workspace in front of models built by OpenAI, Anthropic, Google and others rather than a model of its own. That request is handled under that provider terms. The advantage of the multi-model shape is that you can route sensitive work to a different provider without switching tools.
How do I delete my chat history?
Individual conversations and uploaded files can be deleted directly, without touching the rest of the account. For everything at once, account deletion at whizi.io/account-deletion removes conversations, messages, uploaded and generated media, saved memory, usage state and the authentication account, subject to a limited retention window described in the privacy policy.
Is my data deleted if I cancel?
No. Cancelling stops billing and ends access at the end of the paid term, but the account and its contents remain, which is what allows you to resubscribe later and find your history intact. If you want the data removed as well, use account deletion, which is a separate action.
Can my colleagues see my conversations?
Not unless you deliberately share one. Conversations are private to your account, and sharing creates an explicit read-only public link for a single conversation that you can revoke at any time. There is no implicit team visibility.
