Tier Privacy Policy

Effective Date: October 28, 2026

Introduction

Tier's privacy policy (the "Privacy Policy") explains the information we collect, how we use and share it, how to manage your privacy controls, and your rights in connection with our websites and the related mobile applications and services (collectively, the "Services"). Tier is headquartered in San Francisco, California, USA. Otherwise, the Services are provided to you by Tier Innovations, Inc. Throughout these Terms "Tier" refers to the relevant service provider providing the Services to you.

If you have any questions about our privacy practices, this Privacy Policy, or would like to contact us:

Information Tier Collects

Tier collects information about you, including information that directly or indirectly identifies you, if you or other Tier users choose to share it with Tier. The sources from which we collect this personal information fall into three categories: information you provide, information we collect automatically, and information we collect from other sources.

Account, Profile, and User Activity

We collect account information such as your name, email address, date of birth, gender, weight, username and password that helps secure and provide you with access to our Services.

Location Information

We collect and process location information when you sign up for and use the Services. We do not track your device location while you are not using the Services.

Content You Share

We gather information from photos, videos, posts, comments, messages, reactions, ratings, reviews, and other content you share on the Services.

How Tier Uses Information

To provide the Services

We use the information we collect and receive to provide the Services, including providing you with the ability to record your activities and analyze your performance.

To customize your experience

We use the information we collect and receive to customize your experience.

To protect you and the Services

We use the information we collect and receive to protect users, enforce our Terms of Service, and promote safety.

To power optional AI features

When you ask for AI coaching, a weekly read, a generated routine, or a coach chat reply, we use your training information to produce that response. See "Artificial Intelligence Features" below.

Artificial Intelligence Features

Tier offers optional AI-powered features, including coaching feedback on your goals, a weekly read on your training, AI-generated workout routines, and a coach chat. These features never run on their own. They run only when you ask for them.

What we send

When you use an AI feature, we send a summary of your own training data to our AI provider: exercise names, weights, reps, dates and session counts drawn from workouts you have logged, any goals you have set, and, in the coach chat, the messages you write together with the recent messages in that conversation. We do not send your password. We do not send other users' training data.

Who processes it

AI features are processed by Google Cloud's Vertex AI using Google's Gemini models. Under Google Cloud's terms, data submitted to Vertex AI is not used to train Google's models.

What we keep

Coaching verdicts and weekly reads are saved with your account so we can show them to you again without repeating the request, and they are deleted when you delete your account. Coach chat history is stored only on your device; we do not keep a copy on our servers, and it is removed if you delete the app or clear its storage. We also record how many AI requests you make, so that we can apply usage limits.

Your choices

AI features are optional. If you do not use them, none of your training data is sent to our AI provider.

Accuracy

AI-generated coaching, insights and routines are automated suggestions. They can be wrong or incomplete, they are not medical or professional advice, and you should not rely on them in place of a qualified coach or physician.

Analytics, Advertising Measurement and Purchases

We use a small number of service providers to understand how the Services are used, to measure whether our advertising works, and to process subscriptions. They act on our behalf and are not permitted to use your information for their own purposes.

Product analytics

We use PostHog to record how the app is used, such as which screens are opened and when you sign up, complete a workout or start a subscription. These events are linked to your Tier account number. We do not send your name, email address, or the contents of your workouts to PostHog.

Advertising measurement

We use Singular, and Apple's AdServices framework through RevenueCat, to learn whether an install of Tier came from one of our ads or links (for example on the App Store, Reddit, TikTok, Instagram or Facebook). When the app is first opened, it shares technical information such as device type, operating system version, app version and IP address, together with a small number of in-app events (signing up, completing a workout, starting a subscription) linked to your Tier account number. We use this only to count and improve our own advertising. Ad platforms we advertise with may receive install and event results so they can report on our campaigns; they never receive your name, email address, or the contents of your workouts. We do not use your device's advertising identifier, we do not ask for permission to track you across other companies' apps and websites, and we do not do so.

Purchases

Subscriptions are sold and billed by Apple. We use RevenueCat to confirm your purchase and manage access to paid features. We never receive your payment card details.

How Information is Shared

We do not sell personal information or aggregated data for monetary value. We may share personal information in accordance with your preferences, as needed to run our business and provide the Services, including with the service providers described above.

Managing Your Privacy Settings

Tier offers several features and settings to help you manage your privacy and share your activities. Most privacy controls are located in your privacy controls page.

Deleting Information and Accounts

You can delete your account at any time from Settings in the app. Deletion is immediate and irreversible: we remove your profile, workouts, sets, personal records, health entries, friendships, routines, saved AI coaching and notifications from our live systems. We keep only the records we are required to retain for legal or accounting reasons, such as proof of a subscription payment, and those are kept separately from your account.

To request a copy of your information instead, write to us at the address below. See “How to Exercise Your Rights”.

Children's Privacy

Our Services are not intended for, nor directed to, children under 13 years of age. If you are under 13, do not use the Services. If you are in the European Economic Area or the United Kingdom, you must be at least 16 to use the Services, or the minimum age of digital consent in your country if it is lower.

Your Legal Rights

Depending on where you live, privacy law gives you rights over the personal information we hold about you. The two sections below describe those rights for users in the European Economic Area, the United Kingdom and Switzerland, and for residents of California. Wherever you live, you can delete your account and all of its data from inside the app at any time, and you can write to us at the address in the Introduction.

Who is responsible for your information

Tier Innovations, Inc. is the controller of the personal information described in this Privacy Policy. Our address and contact details are in the Introduction above.

Your Rights in the European Economic Area, United Kingdom and Switzerland

If you are in the EEA, the UK or Switzerland, the General Data Protection Regulation and the UK GDPR give you the rights described here.

Why we process your information, and on what legal basis

Health information

Some of what you can record in Tier — bodyweight, sleep, energy, how hard a session felt, and your general state of mind — is health data, which the GDPR treats as a special category (Article 9). We process it only with your explicit consent, given when you choose to fill in those fields. They are optional, you can leave them blank, and you can withdraw that consent at any time by deleting the entries or your account. Health entries are visible only to you; they are never shown to your friends or on your profile.

Your rights

We do not use your personal information to make decisions about you that produce legal or similarly significant effects without human involvement. The AI features produce training suggestions only.

Where your information is held

Tier is operated from the United States, and our service providers store and process information there. When we transfer personal information out of the EEA, the UK or Switzerland, we rely on the European Commission's Standard Contractual Clauses, and the UK Addendum where applicable, which our providers have entered into with us.

How long we keep it

We keep your account information for as long as your account exists. When you delete your account we delete your personal information from our live systems immediately, except for records we are required to keep for legal or accounting reasons, such as proof of a subscription payment.

Your Rights Under California Law

If you are a California resident, the California Consumer Privacy Act, as amended by the California Privacy Rights Act, gives you the rights described here.

What we collect

In the past twelve months we have collected the following categories of personal information, all of which are described in more detail in “Information Tier Collects” above: identifiers, including your name, email address, username and account number; characteristics such as your date of birth and gender; commercial information about subscriptions you have purchased; internet and app activity, including the screens you open and the features you use; approximate location, in the form of the city and gym you choose to associate with your account; and health and exercise information, including your workouts, bodyweight and the optional entries described above.

We collect this information from you, automatically from your use of the app, and from the service providers listed in “Analytics, Advertising Measurement and Purchases” above. We use it for the purposes set out in “How Tier Uses Information”.

Sensitive personal information

Health and exercise information is sensitive personal information under California law. We use it only to provide the Services you have asked for — recording your training, showing your history and progress, and producing the optional AI features when you request them. We do not use or disclose it to infer characteristics about you, and we do not use it for any purpose that would give you the right to limit its use under Section 1798.121.

We do not sell or share your personal information

We do not sell your personal information, and we do not share it for cross-context behavioural advertising, as those terms are defined by California law. We have not done so in the past twelve months. We do not have actual knowledge of selling or sharing the personal information of anyone under sixteen years of age. We do not use your device's advertising identifier and we do not track you across other companies' apps and websites.

Your rights under California law

You can use an authorised agent to make a request on your behalf. We will ask the agent for proof that you gave them permission, and we may still ask you to verify your own identity.

How to Exercise Your Rights

To delete your account and everything in it, open Settings in the app and choose Delete Account. This takes effect immediately and cannot be undone.

For any other request — access, a copy of your data, correction, restriction, portability, or objection — write to us at tierinnovationsinc@gmail.com with the email address on your Tier account and a description of what you want. We will ask you to confirm your identity from that email address so that we do not disclose your information to someone else.

We respond to requests within thirty days. Where a request is complex, or where you have made several, we may extend that period and will tell you if we do. There is no charge for making a request, unless it is manifestly unfounded or excessive.
