Terms of Service

A Creative Work by Letterbox Apps
Last updated: 11 November 2025

Important: doit is a glorified calculator for invoices & expenses.

It is NOT accounting software, tax software, or legally binding invoicing.

You are responsible for GST, tax, and legal compliance.

Subscription & Payment

How It Works

  • Monthly billing via Stripe (NZD)
  • Free access via coupon codes
  • Payment required upfront
  • Auto-cancel after 3 failed payments

Cancellation

  • Cancel anytime, no questions asked
  • Access until end of paid month
  • No refunds after purchase
  • Card fails 3 times = auto-cancel

No Refunds Policy

We give you full access immediately and let you export everything. We're a tiny operation, so we can't process refunds.

Your Data

  • Export everything in CSV anytime – no limits, no gatekeeping
  • Delete account + all data permanently anytime – it's gone forever
  • No lock-in. No recovery after deletion. We mean it when we say you own your data
  • Regular backups recommended – we provide one-click backup tools

Email Delivery

You have two options for sending invoices:

  • Use letterbox.co.nz servers – Rate-limited to prevent abuse
  • Use your own SMTP server – Full control, your reputation

Important: We are not liable for email delivery failures or spam filter issues. Email is complicated.

Your Responsibilities

  • Keep your login credentials secure
  • Use the service legally (no fraud, no abuse)
  • Don't attempt to hack or break our systems
  • Verify your financial data with your accountant
  • Comply with GST, tax, and legal requirements in your jurisdiction

Limitations & Liability

Service Availability: We work hard to keep doit running, but we can't guarantee 100% uptime. Back up your data regularly.

  • Liability cap: Maximum 3 months of subscription fees
  • Not liable for: Lost business, indirect damages, or data loss
  • Provided "as is" – We're a small team doing our best
  • No warranty on accuracy of calculations or reports

Disputes: New Zealand law applies. Any disputes resolved in Auckland courts.

Account Termination

We can suspend or terminate accounts that:

  • Violate these terms
  • Are used for illegal activities
  • Abuse or attack our systems
  • Have unresolved payment issues

Grace period: You have 30 days to export your data after termination.

Changes to Terms

We'll email you at least 30 days before any major changes. Continuing to use doit after changes means you accept them.
