Tierly privacy policy

Updated 23 October 2026. Tierly is operated by McNut. Contact: support@mcnut.net.

Information we process

When you sign in with Google, we receive your account identifier, name, email address and profile image. We store your Tierly profile, lists, uploaded item images, rankings, votes, list participation, friend relationships and activity notifications to provide the service. You choose which images and list content to upload.

Our hosting and authentication providers process technical information such as IP address, browser information, request times and security logs for service delivery and abuse prevention. Session cookies keep you signed in. Searches are sent to our servers to return matching lists and may appear in request logs. Tierly does not request GPS or device-location access.

If you enable device notifications, we store that browser’s push endpoint, encryption keys and notification preferences to deliver updates through its notification provider. Lock-screen messages do not include names, list titles or individual votes. You can change preferences or turn notifications off in Profile; signing out unsubscribes that browser. Queued deliveries expire after one hour and are removed when processed.

How information is used and shared

We use this information to operate Tierly, save and synchronise your lists, support collaboration, respond to support requests and protect the service. Google provides sign-in. Cloudflare hosts the app, stores account and list records in D1, and stores uploaded images in R2. These providers process information to deliver their services and may process it outside your country.

Friends and list participants can see the profile and list information exposed by the features you use. Public templates and rankings are visible to others. Shared links can be passed on. Uploaded item image URLs are publicly retrievable by anyone who has the URL; do not upload sensitive or private images.

With your permission, PostHog processes page visits, selected actions and an opaque identifier in its EU cloud. List names, rankings, votes and invitation codes are not intentionally collected. You can change your choice on this device below. We do not sell your personal information or use it for targeted advertising. Google’s authentication and data services are described in Google’s privacy policy.

Your choices and retention

You can manage lists and sharing in the app, sign out, and request access, correction or deletion by contacting support. We retain account and content data while needed to provide your account, unless you delete it or request deletion. Limited records may be retained for security or legal obligations.

Request account or data deletion. Deleting Tierly does not delete your Google account or copies that other people have independently saved.

Children and changes

Tierly is intended for people aged 16 and over. Please contact us if you believe a child has supplied personal information. We may update this policy as the service changes and will publish the current version here.
