Privacy Policy

Overview

This Privacy Policy explains how SoluLab ("SoluLab," "we," "us," or "our") collects, uses, and protects information when you use the Tax Set mobile application and related services (collectively, the "Service"). Tax Set helps independent workers estimate and track a tax set-aside reserve. By using the Service, you agree to the collection and use of information as described in this policy.

Information We Collect

We collect the following categories of information:

• Account information — name, email address, and authentication credentials when you create an account.
• Financial and transaction data — income, expenses, and transaction records you enter manually or import by connecting a bank or card account through our banking data provider.
• Tax profile information — filing state, estimated payment history, and other inputs used by the deterministic tax engine to calculate your reserve.
• Classification and override data — how transactions are classified, any corrections you make, and any manual overrides you enter, including the reason you provide.
• Usage and device information — app interactions, crash reports, device type, and operating system, collected through analytics and crash-reporting tools.
• Subscription and billing information — purchase and entitlement status from the App Store or Google Play, processed through our subscription-management provider. We do not receive or store your full payment card details.
• Referral information — referral codes, invite links, and attribution data if you participate in our referral program.

How We Use Your Information

We use the information we collect to:

• Calculate and continuously update your tax set-aside reserve, safe-harbor status, and deadline tracking;
• Classify transactions, generate plain-language explanations of reserve changes, and produce quarter-end forecasts;
• Maintain your calculation history and audit trail, and generate CPA-ready exports at your request;
• Provide customer support and respond to your requests;
• Send push notifications about meaningful reserve changes or approaching deadlines, and reminders you configure in Settings;
• Detect, prevent, and address technical issues, fraud, and abuse;
• Operate our subscription, referral, and cross-promotion features; and
• Improve the Service, including transaction-classification accuracy over time.

Third-Party Services

We work with the following categories of service providers to operate Tax Set:

• Bank/card data connectivity — to securely link accounts and retrieve transaction data on your behalf.
• Cloud infrastructure and analytics (e.g. Firebase) — for app analytics, push notifications, and crash reporting.
• Attribution (e.g. AppsFlyer) — to measure install attribution and support deep links and referrals.
• Subscription management (e.g. RevenueCat) — to verify purchases and manage entitlements alongside the App Store and Google Play.
• Email delivery — to send password-reset and account-related emails.
• AI service providers — to power classification, explanation, and forecast features, as described below.
• Advertising mediation — where applicable, to display in-app advertising.

Each provider only receives the data necessary to perform its specific function and is contractually restricted from using your data for unrelated purposes.

AI Features

Certain features — transaction classification, change explanations, and income-volatility forecasting — are powered by AI models operated by our AI service provider. Transaction and account data relevant to the specific request may be sent to that provider to generate a response. Manual overrides you enter are treated as your own statement and are excluded from any classification-improvement pathway. AI outputs never replace or override the deterministic tax engine's calculated reserve figure.

Data Sharing

We do not sell your personal information. We share information only: with the service providers listed above to operate the Service; with your CPA or accountant when you explicitly generate and share an export; to comply with legal obligations or valid legal requests; to protect the rights, property, or safety of SoluLab, our users, or the public; or in connection with a merger, acquisition, or sale of assets, subject to continued protection under a policy at least as protective as this one.

Data Security

We use industry-standard safeguards to protect your information, including encryption of sensitive data such as bank connection credentials, access controls, and secure transmission (HTTPS/TLS) for data in transit. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

Data Retention

We retain your account and financial data for as long as your account is active or as needed to provide the Service, including your calculation history and audit trail, which is retained in full for your own reference and export. You may request deletion of your account and associated data at any time, subject to any legal or regulatory retention requirements.

Your Choices

• Access and correction — you can review and correct classification and override data directly in the app.
• Notifications — you can manage push-notification and reminder preferences in Settings.
• Account deletion — you may request deletion of your account by contacting us at the email below.
• Disconnecting accounts — you can disconnect linked bank or card accounts at any time from Settings.

Children's Privacy

Tax Set is not directed to individuals under the age of 18 and is not intended for use by anyone not old enough to independently earn 1099 income. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last updated" date above and, where appropriate, through an in-app notice.
