Your client documents stay on your computer.

Form filling runs locally. Preparing a custom template is a separate cloud-assisted step. Here is what happens to your information in each case.

Filling a form

Client PDFs, scans, photos, Word files and typed notes are processed by a model running on your own computer. Client documents are not uploaded or sent to a cloud AI provider. Filled PDFs and your edits are saved locally. Local filling does not require an account or an API key.

The local model downloads once, about 5 GB, the first time you fill a form. After setup, filling works offline.

Adding a new form

If you add your own form, the blank fillable PDF and your setup instructions are sent to Fyllyo’s cloud service to prepare the template. No API key is required. Client source documents are not included. Use a blank form without client details, and keep personal client information out of your instructions.

Template setup uses a cloud AI provider. That provider receives the blank form and setup instructions needed to prepare the template. Subsequent filling uses the template locally. You can optionally configure your own provider API key; that provider’s terms, privacy policy and usage charges then apply to your setup requests.

Website feedback and waitlist requests

When you submit feedback or join the document workflows waitlist, your message and any email address you provide are sent through Resend to the Fyllyo team’s support inbox. This website submission is separate from local document processing. Do not include client documents or personal client information.

We use feedback to respond to requests and improve Fyllyo. If you join the waitlist, we use your email to contact you about the upcoming document workflows product. Waitlist requests are managed by our team; they are not purchases. Contact support@fyllyo.com to unsubscribe or request deletion of your inquiry. See Resend’s privacy policy for its processing practices.

This website

The website is separate from local form filling. It uses Ahrefs Analytics for website usage measurement. That service receives website interaction and technical information. The website does not accept client documents.

Read the Ahrefs privacy policy for its practices. The interactive examples on the homepage use fictional data and do not process or upload files.

Questions?

You manage and delete source documents and filled PDFs on your computer. Deleting a website inquiry does not delete those local files.
