Privacy

Last updated November 2, 2026

Accio Patent is published by Driven Leaf, LLC (“we”). The app is designed so that we don’t know who you are or which patents you fetch. That isn’t a promise about how carefully your data is handled: it’s a statement that the data never reaches us in the first place.

The app

Accio Patent has no accounts and no sign-in. It contains:

• No analytics.
• No advertising.
• No third-party code, tracking or otherwise.

Where your searches go

When you fetch a patent, the app sends its number directly to a patent office: the European Patent Office (EPO), through its Open Patent Services and its Publication Server, or the United States Patent and Trademark Office (USPTO). A patent’s family, legal status, and citations come from the EPO the same way. Those offices receive the request and are subject to their own privacy practices, which we don’t control. The request identifies the app, not you. The one exception is a USPTO key of your own: if you add one, it’s kept in your iCloud Keychain and sent only to the USPTO, and requests made with it identify your USPTO account.

The token service

The EPO asks each app that uses its data service to identify itself with an access token, and the app gets one from a small service we run on this server. It’s the only server of ours the app talks to, and it hands out tokens and nothing else:

• It never sees a patent number, a search, or anything you fetch. Those go directly from your device to the EPO or the USPTO.
• It keeps no IP addresses and no log of requests.
• It doesn’t know who you are. It uses Apple’s App Attest to check that a request comes from a genuine copy of the app, and keeps only what that check needs and a count of the tokens it hands out.

On your device

• The scanner reads camera images on your device. They’re never stored and never sent anywhere.
• The text of a patent is read from its PDF on your device, and a patent in another language is translated into English on your device, by Apple’s own translation. Your device may download a language from Apple to translate it.

iCloud

Your Library, with its tags, notes, and highlights, and the PDFs you fetch sync through your own iCloud account, in the app’s private space there, under Apple’s privacy policy. We have no access to it and can’t see what’s in it.

Subscriptions

Accio Patent Premium is an in-app purchase handled entirely by Apple. Payment details go to Apple and never to us. We receive Apple’s standard sales and subscription reports, which don’t identify individual customers. See Apple’s privacy policy.

This website

acciopatent.com collects nothing. It’s a set of static files served from a server we run. It has:

• No analytics.
• No cookies.
• No advertising, tracking pixels, or fingerprinting.
• No third-party scripts, fonts, or embeds. Every file the site loads comes from acciopatent.com.

As with any web server, requests appear in server logs, which include an IP address and are used only to keep the site running and secure. They aren’t analyzed to build a picture of visitors, and they aren’t shared.

Support email

If you email support@drivenleaf.com, we use what you send only to reply to you. The app’s Send Feedback and Report a Problem start the message with details that help us answer, and you can read and change them before you send it.

Children

Accio Patent is a professional tool and isn’t directed at children. It knowingly collects no personal information from anyone, including children.

Changes

If this policy changes, the date at the top of this page changes with it.
