Privacy Policy

1Introduction

Housatonic Holdings operates RentalMath. This Privacy Policy explains how we collect, use, disclose, and protect your information across all subscription tiers. By using the App, you agree to this Policy.

2Information We Collect by Tier

Free Tier (No Account)

No personal information is collected or transmitted to our servers. Deal data is stored only in your browser's localStorage on your device. We have no access to this data.

Paid and Premium Tiers (Account Required)

• Account information: email address, authentication credentials (managed by Firebase Authentication). If you sign in with Google or Apple, we receive your name and email from those providers.
• Deal data: all property records you sync to Firestore, including addresses, financial inputs, notes, and timestamps.
• Billing information: your subscription tier, billing dates, and payment status. Full payment card details are processed and stored by Stripe, not by us.
• Technical data: IP address, device type, browser, and usage event logs collected by Firebase infrastructure.

3How We Use Your Information

• To provide, maintain, and improve the App across all tiers.
• To authenticate your identity and secure your account.
• To process subscription payments through Stripe.
• To sync your deal data across your devices (Paid and Premium).
• To power AI features using your deal inputs (Premium; inputs are not retained for model training without your consent).
• To send billing confirmations, renewal reminders, and data-deletion warnings.
• To respond to support and privacy requests.
• To comply with legal obligations.

4How We Share Your Information

We do not sell your personal information. We share data only as follows:

• Stripe: payment processing. See stripe.com/privacy.
• Google Firebase/Firestore: cloud authentication and deal data storage.
• Google Sign-In / Apple Sign-In: authentication confirmation when you use social sign-in.
• CDN providers (jsDelivr, Google Fonts): your browser downloads App assets from these providers; they may log IP addresses.
• URL shortening services: the shareable deal URL when you use the shortening feature.
• Law enforcement or legal process: if required by applicable law.

5Data Specific to Each Tier

Free Tier

No data leaves your device. localStorage is cleared when you clear browser data. We have no visibility into free-tier usage.

Paid and Premium Tiers

Deal records are stored in Firestore and retained for the life of your account plus a 30-day grace period after subscription lapse or account deletion request. See the Data Retention & Deletion Disclosure.

Premium AI Features

When you use AI-powered features, your deal inputs are sent to our AI inference layer to generate estimates. We do not use your deal inputs to train or fine-tune AI models without your explicit consent. AI query logs may be retained for a limited period for debugging and quality assurance.

6Billing Data and PCI Compliance

We do not store, process, or transmit full payment card numbers. All payment processing is handled by Stripe, a PCI-DSS Level 1 certified payment processor. We receive only non-sensitive billing metadata from Stripe (subscription status, last-four digits of card, billing dates).

7Data Security

We implement reasonable security measures including HTTPS, Firebase Authentication token management, and Stripe's PCI-compliant payment infrastructure. No system is completely secure; we cannot guarantee absolute security of data transmitted over the internet.

8Children's Privacy

The App is not directed to children under 13 (or 16 where applicable). We do not knowingly collect information from children. Contact admin@housatonicholdings.com to report a concern.

9Your Rights

See the Consumer Privacy Rights Notice for jurisdiction-specific rights (CCPA, GDPR, etc.) and how to exercise them. To export your data, use the App's export feature. To delete your account and data, see the Data Retention & Deletion Disclosure.

10Third-Party Services

See the Third-Party Services Disclosure for a full vendor list, what data each receives, and links to their policies.

11Changes

We may update this Policy. We will post the revised version with a new effective date. Material changes will be communicated to registered users by email where feasible.
