We take the security of customer data very seriously at CodeConvert AI. This page contains a summary of our privacy policy regarding our customer's code data, specifically, their input code and the generated output from CodeConvert AI.
Free Tools (Without Logging In)
For the free tools used by our users before logging in, we store the input and the results in our database to enable sharing via a shareable link. You can delete this data using the 'Delete my data' button that appears on the results page — this button is available on the same browser where you generated the result. Once deleted, the shared link will no longer work and the code data is permanently removed from our servers.
For a better user experience, we also store the user's last used input code locally in the browser. This data never leaves your device.
Logged-In Users
For logged-in users, your code and results are stored in the cloud by default to power the History feature, which lets you revisit past conversions, generations, and explanations. You can switch to local-only storage at any time from your Account settings. When using local storage, none of your code is stored on our servers.
You can delete individual history entries from the History page at any time. If you switch from cloud to local storage, previously saved cloud history entries can also be deleted from the History page.
Improving result quality: we may use cloud-stored history internally to measure and improve the accuracy and completeness of our results across our tools — for example, to detect cases where output is incomplete and to evaluate fixes. This is strictly internal evaluation; your code is never used to train AI models and is never sold or shared for advertising. Access is limited and restricted to this purpose. If you delete a history entry (or switch to local-only storage and delete your cloud history), it is removed from this use. You can opt out at any time from your Account settings, and opted-out history is excluded. This setting only applies to cloud-stored history; with local-only storage, none of your code reaches our servers.
Uploaded Files
When users upload files or zip folders through the Files page to provide additional context for AI responses, this information is stored and processed to provide the service. Files marked AI Visible may be used as context for AI responses, and relevant content may be shared with our configured AI service providers. Users maintain control over their data - if a user deletes a file from the Files page, all associated code and information are permanently removed from our database and servers.
Third-Party AI Providers
Your code is sent to third-party AI providers for processing via Vercel AI Gateway, a routing layer that forwards requests to the configured AI provider.
By default, AI requests are sent with Zero Data Retention (ZDR) enabled and with prompt training disallowed. Vercel does not retain your prompts or outputs beyond the duration of the request, and downstream providers are instructed not to use your data to train their models. We do not sell your code.
Where a Zero Data Retention host exists, we use it. If that host is unavailable, some Advanced models may run on a no-training host that retains prompts and outputs for up to 30 days for abuse and safety monitoring. Those models are marked in the picker. Auto will not select them.
The AI providers we currently use — including OpenAI, Anthropic, Google, Mistral, Fireworks AI, and Baseten — are instructed not to use your data for training. Open-model requests are pinned to US-based hosts (Fireworks AI and/or Baseten) via the Vercel AI Gateway.
AI Output Watermarks
We do not add a watermark to generated output. Some AI providers may apply an invisible, statistical watermark at the model layer. If present, that mark is applied by the provider. We cannot turn it off, we cannot independently verify it, and we do not control when a provider changes it. It cannot be stripped without rewriting the text.
Provider practices vary and can change. If this matters to you, review the provider's own documentation for the model you select, or choose a different model in the picker.
