Free Height Outlook

You can use the free Height Outlook without creating an account.

The calculator uses information you enter, including your age, growth-reference sex, current height, and optional parent heights, to calculate your Height Outlook. These calculations are deterministic and run in your browser.

We may store your preferred unit and temporary calculator information in your browser so the site works as expected and, when applicable, so your calculation can continue through sign-in and purchase.

Information entered into the anonymous calculator is not saved to a See You Taller Growth Tracker profile unless you choose to save and track it.

Google sign-in and account information

If you use Growth Tracker, you sign in with Google. See You Taller uses Supabase Auth to manage authentication.

We may receive and store information associated with your Google sign-in, such as:

• your account identifier;
• email address;
• display name; and
• profile image.

We use this information to authenticate you, associate your Growth Tracker purchase and saved data with your account, restore access across devices, and display your account controls.

Growth Tracker information

If you use Growth Tracker, we may store information you choose to provide, including:

• profile nickname;
• birth month and year;
• growth-reference sex;
• optional parent heights;
• preferred unit;
• measurement dates and heights; and
• calculated percentile and forecast history.

We use this information to provide saved profiles, measurement history, growth charts, growth calculations, and forecast history.

A nickname does not need to be a legal name, and we recommend using a nickname or other non-sensitive label.

Payments

Growth Tracker is a $7.99 one-time purchase processed through Stripe.

Payment-card information is entered into and processed by Stripe. See You Taller does not store your full payment-card number.

We may retain information about your transaction, such as payment status, amount, currency, Stripe transaction identifiers, and purchase date, so that we can confirm your purchase, maintain your Growth Tracker entitlement, provide support, and handle refunds or payment disputes.

Stripe may retain payment and transaction information according to its own policies and legal obligations.

Routine technical information

Like most web services, See You Taller and its hosting and infrastructure providers may process routine technical information when you use the site, such as IP address, browser or device information, request information, timestamps, and security or diagnostic information.

We use this information as necessary to operate, secure, troubleshoot, and maintain the service.

We do not currently use a separate product analytics service. If we introduce analytics or other tracking technologies that materially change the information we collect or how we use it, we will update this Privacy Policy as appropriate.

Service providers

We use third-party service providers to operate See You Taller:

• Supabase provides authentication and database infrastructure.
• Google provides Google Sign-In.
• Stripe processes payments.
• Vercel hosts and delivers the application.

These providers may process information on our behalf or independently as necessary to provide their services.

How information may be shared

We do not sell your Growth Tracker profile or measurement information.

We may disclose information:

• to service providers as necessary to operate, host, secure, authenticate, support, and process payments for See You Taller;
• when necessary to investigate fraud, abuse, or security incidents;
• when required by law, legal process, or a valid governmental request; or
• in connection with a merger, acquisition, financing, sale, or other transfer of all or part of the business, subject to applicable law.

We do not share Growth Tracker profile or measurement information with third parties for their own advertising purposes.

Retention

We generally keep account and Growth Tracker information while your account remains active or until you request deletion.

We may retain limited information for longer when reasonably necessary for security, fraud prevention, dispute resolution, enforcement of our agreements, or compliance with legal, tax, accounting, or other obligations.

Third-party providers may have their own retention requirements. In particular, payment providers may be legally required to retain certain transaction information after you delete your See You Taller account.

Security

We use reasonable technical and organizational measures intended to protect information handled by See You Taller. However, no internet transmission or storage system can be guaranteed to be completely secure.

Access to saved Growth Tracker information requires authentication, and our database infrastructure uses access controls intended to restrict users to information associated with their accounts.

Children and account ownership

The free Height Outlook can be used without creating an account.

See You Taller accounts are intended for people age 13 or older. Children under 13 should not create or control their own See You Taller account.

A parent or guardian may use their own account to create and manage a Growth Tracker profile for a child under 13.

If you believe a child under 13 has created an account or provided personal information to us without appropriate parental involvement, please contact us so we can review and, where appropriate, delete the information.

Delete your account and data

Removing a Growth Tracker profile deletes only that profile. Full account deletion permanently removes your See You Taller account and all user-controlled profiles and growth data associated with it.

Signed-in users can use the authenticated account deletion feature:

Delete your See You Taller account and data

Account deletion removes user-controlled See You Taller profiles and measurement history and deletes the associated Supabase Auth account after the required authentication confirmation.

Deletion from See You Taller does not necessarily delete information independently maintained by third-party providers, such as Google or Stripe, or records that we or a provider must retain for legal, security, fraud-prevention, tax, accounting, or dispute purposes.

Your choices

You can use the free Height Outlook without creating an account.

You can choose not to provide optional parent-height information. You can also clear locally stored See You Taller information using your browser's storage controls, although doing so may reset preferences or temporary calculator state.

You may request deletion of your See You Taller account and saved Growth Tracker information as described above.

For questions about access, correction, deletion, or account-data issues, contact us at bitcrossing@gmail.com.

Changes to this Privacy Policy

We may update this Privacy Policy as See You Taller changes. When we make changes, we will update the “Last updated” date above. If a change materially affects how we handle personal information, we will provide additional notice when appropriate.
