Your images deserve clear answers.

1. How image processing works

When you select Convert, your browser sends the selected HEIC or HEIF file to the HEICConverter API. The server decodes the source image and creates a new file in the output format you selected. For a batch, the files are processed and returned together as a ZIP download.

Image conversion is performed on the server. Your browser must be connected to the internet to upload files and receive the converted result.

2. What information is involved

• Images you choose: the HEIC or HEIF files you submit for conversion.
• Conversion settings: the requested output format and, where supported, the quality setting.
• Temporary processing data: working copies and intermediate files needed to decode and encode the image.

The current application does not provide user accounts, a personal image library or a conversion-history feature. This does not mean that the hosting platform or network infrastructure never creates operational logs.

3. Temporary files and deletion

The conversion service creates a temporary directory for each conversion job. Its cleanup routine attempts to delete the files in that directory after processing, including when conversion fails.

Cleanup is best-effort: a server shutdown, filesystem problem or infrastructure-level copy may prevent immediate removal. Do not treat this workflow as a guaranteed secure-erasure service, and do not upload files that require a certified deletion process.

4. Hosting, network and third-party infrastructure

The deployed application runs on hosting and network infrastructure. Those providers may process technical information such as request metadata, security events, diagnostic logs or backups under their own configurations and retention policies.

The exact retention and processing practices depend on the hosting provider and deployment configuration. This notice does not claim that infrastructure logs or backups are never created or retained. Review the relevant provider policies for details.

5. Your choices and responsibilities

• Only upload images you own or have permission to process.
• Avoid uploading sensitive, confidential or highly personal images unless you have assessed the risks and are comfortable with the deployment's data handling.
• Use the service over a secure HTTPS connection when it is deployed with HTTPS.
• Keep your original image if you may need its original data or metadata later.
• Download your converted result and remove local copies you no longer need.
