Privacy Policy

1. Overview

This Privacy Policy explains how TechInterface LLC collects, uses, shares, stores, and protects information when you use GrowPIK, our websites, mobile apps, account flows, subscriptions, support tools, and learning features.

GrowPIK is a family-focused educational math product. Adult account holders, parents, or guardians may create and manage family workspaces and learner profiles. Learners may use the service under the supervision or authorization of a parent, guardian, school, or other responsible adult as applicable.

2. What Information We Collect

The information we collect depends on how you use GrowPIK, which account features are enabled, and which device or platform you use.

• Account information, such as name, display name, email address, sign-in method, authentication identifiers, account role, family relationship, password reset state, and similar account-management details.
• Family and learner profile information, such as learner name, grade level, active learner selection, family workspace settings, and profile preferences entered by an account holder.
• Learning and progress information, such as worksheets opened or completed, answers, drawings or handwriting inputs, placement activity, concept progress, mastery state, learning history, rewards, streaks, and tutor or help interactions connected to learning.
• Support and contact information, such as support requests, issue reports, email messages, support chat questions, optional attachments, and diagnostic details you choose to include.
• Billing and subscription information, such as plan selection, trial status, subscription status, entitlement limits, purchase history metadata, Stripe customer or subscription identifiers, Google Play purchase data, Apple App Store purchase data, and related order or renewal status. Payment card numbers are processed by payment providers and are not stored directly by GrowPIK.
• Device, browser, app, and usage information, such as IP address, request logs, app version, device type, operating system, browser type, crash or diagnostic information, local storage identifiers, access tokens, refresh tokens, and similar technical information used for authentication, security, reliability, and troubleshooting.
• Third-party sign-in information, such as identifiers, email address, and profile claims provided by Google, Apple, or another sign-in provider when you choose to use that sign-in method.

3. How We Use Information

We use information to operate GrowPIK, support families and learners, keep the service secure, and improve the product.

• Create, authenticate, and manage accounts, family workspaces, learner profiles, sessions, and account recovery.
• Deliver worksheets, placement flows, progress tracking, learning history, AI-assisted tutor features, rewards, support workflows, and subscription-gated features.
• Process sign-in, session management, password resets, account recovery, and service security.
• Provide support, respond to reports, and investigate bugs, fraud, misuse, or safety issues.
• Process subscriptions, trials, renewals, cancellations, refunds, billing status, and entitlement access across web, Google Play, and Apple App Store purchase flows.
• Send transactional communications such as password reset emails, support responses, billing notices, product notices, and policy updates.
• Analyze product reliability, app performance, feature usage, and learning experience quality so we can maintain and improve GrowPIK.

4. When We Share Information

We do not sell personal information. We share information only as needed to provide, secure, support, bill for, and improve GrowPIK, or as required by law.

• With service providers that help us operate the product, including hosting, cloud infrastructure, databases, email delivery, authentication, billing, customer support, analytics, monitoring, and AI/model providers.
• With payment processors and app-store billing providers, including Stripe, Google Play, and Apple App Store, to process purchases, renewals, refunds, cancellations, and entitlement verification.
• With sign-in providers, such as Google or Apple, when you choose to use those sign-in options.
• Within a family workspace, where an authorized parent, guardian, or account holder can view and manage learner profiles, progress, assignments, and billing information tied to that workspace.
• When required by law, legal process, or a valid governmental request, or when reasonably necessary to protect rights, safety, users, or the service.
• As part of a merger, financing, acquisition, restructuring, or sale of business assets, subject to appropriate confidentiality and legal safeguards.

5. Service Providers and Third Parties

GrowPIK uses third-party providers to operate the service. These may include Microsoft Azure for hosting, databases, storage, email, and AI-related infrastructure; Stripe for web billing; Google Play for Android subscriptions; Apple App Store for iOS subscriptions; Google and Apple for sign-in; and Google Gemini or other AI/model providers for tutor or learning-help features.

These providers process information for us under their own terms, policies, and security practices. The exact provider mix may change as the product evolves, and we will update this policy when changes are material.

6. Cookies, Browser Storage, and Device Storage

On web, GrowPIK uses browser-based storage such as local storage to keep you signed in and remember app state like the active family or learner context. On native devices, the app uses secure device storage and similar local storage to support the same experience.

We use standard networking, browser, device, and server-log capabilities needed to run the app, secure accounts, diagnose errors, and maintain reliability. We do not use third-party advertising cookies to show behavioral ads in GrowPIK.

7. Children, Learners, and Parent or Guardian Rights

GrowPIK is designed for family and learner use, including guardian-managed learner profiles and student learning flows. Parents and guardians are responsible for creating, approving, or supervising accounts and learner profiles for children who cannot legally consent on their own.

We collect learner information to provide educational features, progress tracking, personalization, support, safety, and account management. We do not knowingly use learner personal information for behavioral advertising.

Parents or guardians may contact us at support@techinterface.net to request access to, correction of, or deletion of learner information associated with their account, subject to identity verification and legal retention requirements.

8. Communications and Notifications

We may send you transactional and service-related communications, such as sign-in support, password resets, support responses, billing notices, legal updates, or product messages related to your account.

If we add optional push notifications, SMS, or marketing communications in the future, we will provide any notices or choices required by law and platform rules.

9. Security

We use technical and organizational measures designed to protect information appropriate to the nature of the service. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

10. Retention, Deletion, and Account Closure

We keep information for as long as reasonably needed to provide GrowPIK, support learners and families, maintain security, comply with legal, tax, accounting, billing, or contractual obligations, resolve disputes, prevent fraud, and enforce our agreements.

You can request account or data deletion by contacting support@techinterface.net. Some records may need to be retained after a deletion request when required for legal compliance, billing reconciliation, fraud prevention, security, dispute resolution, backup recovery, or enforcement of our agreements.

11. International Transfers

TechInterface is based in the United States. Depending on where you use GrowPIK and which providers support the service, information may be processed in the United States or other countries. We use reasonable safeguards appropriate for the service and providers involved.

12. Changes to This Policy

We may update this Privacy Policy as the product and our data practices evolve. If we make material changes, we may notify you through the app, website, email, or another reasonable method.
