GeoLock

Add a location condition to viewing.

Choose an approved area for supported images and files. GeoLock asks the recipient to satisfy the location check before viewing.

No phone number or email required for core Hat use.

The useful difference

A clearer way to handle sensitive work.

01

Define the area

Choose the location and supported radius in the sending flow.

02

A viewing condition

Use location as an additional access condition for suitable content.

03

Plan for device support

Location permission, accuracy and client support affect the recipient’s experience.

How it works

Three deliberate steps.

01

Add supported content

Select the image or file in your Hat channel.

02

Set the approved area

Enable GeoLock and review the location and radius.

03

Explain the requirement

Tell the recipient where viewing is permitted and check that their device supports the flow.

Know the boundary

Choose controls with clear expectations.

GeoLock is an app/service access control, not a guarantee of physical presence. Device compromise, spoofing and poor positioning affect assurance. Location parameters are part of the workflow; do not assume that no location-related data reaches service components. Copies kept after viewing remain outside the lock.

Review the security evidence

Questions, answered

Before you get started.

Where can I use GeoLock?

Open City of Hats to review the controls available for your client, content and plan. The app shows applicable requirements before you proceed.

What should I check before sharing sensitive information?

Verify the recipient, use a supported device and choose appropriate access and retention rules. Review the Security Evidence Center for boundaries and evidence status.

City of Hats is free to use. Feature availability and limits vary by plan and client. Premium is optional; review current limits in the app or on the plans page.
