Privacy Policy

Last updated: February 28, 2026

Introduction

This Privacy Policy ("Policy") explains how Fapbric Technology Solutions ("Company," "we," "us," or "our"), operating the DueDrop service, collects, uses, shares, and protects your personal information when you use our website, application, and related services (collectively, the "Service").

By using DueDrop, you agree to the collection and use of information in accordance with this Policy. If you do not agree with this Policy, please do not use the Service.

We are committed to transparency about our data practices. This Policy is designed to help you understand exactly what data we collect, why we collect it, who we share it with, and what rights you have.

1. Information We Collect

Account Information

Information you provide when creating and managing your account:

  • Full name, email address, and password
  • Business name, phone number, and address (optional)
  • Profile preferences and settings
  • Voice Profile data (communication style preferences and writing samples you provide)

Billing Information

  • Subscription plan selection and billing history
  • Payment card and billing details are processed and stored exclusively by Stripe, our third-party payment processor; DueDrop does not store your credit card numbers or bank account details
  • We receive from Stripe: last four digits of your card, card brand, expiration date, billing address, and payment status

Business Data from Accounting Software

When you connect your accounting software (Xero, QuickBooks, FreshBooks) via OAuth, DueDrop establishes an authorized connection to periodically sync invoice and contact data. We access:

  • Invoice data: Invoice numbers, amounts, due dates, payment status, line item descriptions, and invoice history
  • Client/contact data: Client business names, contact names, email addresses, and phone numbers
  • Organization data: Your business name and basic organization details from your accounting platform

Specific OAuth scopes by provider:

  • Xero: accounting.transactions, accounting.contacts, accounting.settings, accounting.attachments, offline_access
  • QuickBooks (Intuit): com.intuit.quickbooks.accounting
  • FreshBooks: User profile reading, invoice reading/writing, client reading/writing

We do NOT access: bank account details, payroll information, tax filings, employee records, profit and loss statements, or any financial data beyond what is necessary to identify and track invoices. This data is synced periodically and can be manually refreshed. You may disconnect any accounting integration at any time, which revokes the OAuth connection.

Email Data

When you connect your email account via OAuth, DueDrop establishes an authorized connection to send emails from your account and read email threads for AI conversation context. We currently support Gmail, Outlook, Zoho Mail, Yahoo Mail, and custom SMTP. We access:

  • OAuth tokens: Encrypted credentials that authorize DueDrop to act on your behalf. Gmail uses gmail.modify, contacts.readonly, userinfo.email, and userinfo.profile scopes. Outlook uses Microsoft Graph Mail.ReadWrite and Mail.Send scopes. Other providers use equivalent minimal scopes
  • Email content: Sent email content (subject lines and body text) for display in your DueDrop dashboard and for AI conversation context
  • Email metadata: Recipient addresses, timestamps, delivery status, and message IDs
  • Tracking data: Email open events (via tracking pixel) and link click events (via click tracking redirects)
  • Contacts (Gmail only): Read-only access to contacts for recipient auto-complete suggestions

All OAuth tokens for all providers are encrypted using AES-256-GCM before storage. You may disconnect any email integration at any time, which revokes the OAuth connection and queues token deletion.

Usage and Technical Data

  • How you interact with the Service (features used, pages visited, actions taken)
  • Device information (browser type, operating system, screen resolution)
  • IP address and approximate geographic location
  • Log data, error reports, and performance metrics
  • Referral source (how you found DueDrop)

2. Cookies and Tracking Technologies

DueDrop uses a limited number of cookies and similar technologies. We do not use advertising or third-party marketing cookies.

Cookie/Technology Purpose Type Duration
Supabase Auth Token Authentication session management Essential Session / 7 days
Supabase Refresh Token Maintains login state across sessions Essential 30 days
User Preferences Stores UI settings (theme, sidebar state) Functional 1 year
Email Tracking Pixel Detects when a reminder email is opened (1x1 transparent image) Analytics N/A (one-time request)
Click Tracking Redirect Records link clicks in reminder emails before redirecting to destination Analytics N/A (one-time redirect)

Note: We plan to implement product analytics (PostHog) in the future. This Policy will be updated before any analytics tracking is activated. Currently, no third-party analytics cookies are in use.

3. How We Use Your Information

4. AI Processing Disclosure

DueDrop uses third-party AI providers to generate personalized payment reminder emails. We believe in full transparency about what data is processed by AI systems and how.

AI Providers

We use the following AI providers: OpenAI, Anthropic, and Google Gemini. The provider used may vary based on availability, performance, and feature requirements.

Data Sent to AI Providers

When generating a payment reminder email, the following data is sent to the AI provider via API:

  • Invoice details: Invoice number, amount due, due date, days overdue, and payment status
  • Client information: Client business name and contact person's name
  • Your information: Your name, business name, email address, and optionally your phone number
  • Conversation context: Snippets from previous emails in the thread (if available) to maintain conversational continuity
  • Voice Profile: Your custom communication style preferences (tone, formality, writing samples)
  • Custom instructions: Any per-invoice or per-rule notes you provide

How AI Providers Handle Your Data

  • We use AI provider APIs under terms that prohibit the use of your data for model training
  • Data is sent via encrypted API calls, processed in real-time, and not retained by AI providers beyond what is necessary for abuse monitoring (typically up to 30 days per provider policies)
  • DueDrop does not train its own AI models on your data
  • We do not sell, share, or provide your data to AI providers for any purpose other than generating the specific email content you requested

5. Email Tracking Technologies

DueDrop includes tracking technologies in emails sent through the Service to provide you with delivery and engagement analytics:

Open Tracking

A 1x1 transparent pixel image is embedded in HTML emails. When the recipient's email client loads this image, it sends a request to our servers, recording an "open" event with the timestamp. This tracking is not 100% accurate, as some email clients block image loading by default.

Click Tracking

Links in emails are routed through DueDrop's tracking server. When a recipient clicks a link, the click is recorded before the recipient is immediately redirected to the original destination URL. Mailto links and anchor links are not tracked.

Your Controls

  • You can disable open tracking and/or click tracking in your account settings
  • When tracking is disabled, emails are sent without the tracking pixel and without link wrapping
  • You are responsible for disclosing email tracking to recipients if required by applicable law in your jurisdiction

6. OAuth Token Handling

When you connect third-party services (Gmail, Outlook, Xero, QuickBooks, FreshBooks), DueDrop stores OAuth tokens to maintain authorized access. Here is how we protect these credentials:

  • Encryption at rest: All OAuth tokens are encrypted using AES-256-GCM authenticated encryption before being stored in the database
  • Key separation: Encryption keys are stored separately from the database and are not accessible through the application's database layer
  • Minimal access: Tokens are used only for the specific authorized actions you configure (e.g., sending emails, syncing invoices)
  • Automatic refresh: Access tokens are automatically refreshed as needed, without requiring you to re-authenticate
  • Revocable: You can disconnect any integration at any time through DueDrop's integrations page, which revokes the token
  • Deletion: All OAuth tokens are deleted upon account termination, within 30 days

7. Data Sharing and Sub-Processors

We do not sell, rent, or trade your personal information. We share your data only with the following categories of service providers ("sub-processors") as necessary to operate the Service:
