1. Acceptance of Terms

By installing, accessing, or using FlowLane (the "Service"), you agree to be bound by these Terms & Conditions ("Terms"). If you do not agree, you must not use the Service.

The Service is operated by ArystoTech Software & AI Systems Ltd. ("we", "us", or "our"). These Terms constitute a legally binding agreement between you and ArystoTech Software & AI Systems Ltd.

You must be at least 13 years of age to use the Service. By using the Service you represent that you meet this age requirement.

2. Description of Service

FlowLane is a personal Kanban board available as a browser extension for Chrome, Microsoft Edge, Brave, and Vivaldi, and as a web application. The Service is offered under a freemium model:

  • Free Tier — Up to 3 projects stored locally in your browser using chrome.storage.local. No account or internet connection required for core functionality.
  • Premium Tier — Unlimited projects, cloud sync via Firebase Firestore, real-time collaboration, and role-based access control. Requires a paid subscription processed through Paddle.

We reserve the right to modify, suspend, or discontinue any part of the Service at any time with reasonable notice.

3. Accounts & Registration

A user account is required only to access Premium Tier features. You may sign in using Google authentication via your browser's identity API, or GitHub OAuth. You are responsible for:

  • Maintaining the confidentiality of your account credentials.
  • All activity that occurs under your account.
  • Notifying us immediately of any unauthorized use at support@flowlanekanban.com.

We reserve the right to suspend or terminate accounts that violate these Terms.

4. Subscriptions & Billing

4.1 Subscription Plans

Premium access is billed on a monthly or annual basis at the rates displayed on the pricing page. Prices are in USD and do not include applicable taxes, which may be added at checkout.

4.2 Billing via Paddle

All payments are processed by Paddle.com Market Limited ("Paddle"), our Merchant of Record. By purchasing a subscription, you agree to Paddle's Terms of Service and Privacy Policy. Paddle handles payment processing, invoicing, and tax compliance on our behalf.

4.3 Automatic Renewal

Subscriptions renew automatically at the end of each billing period unless cancelled. You authorise us (via Paddle) to charge your payment method on a recurring basis until you cancel.

4.4 Cancellation & Expiry

You may cancel your subscription at any time through the billing portal accessible from within the FlowLane extension or web app. Upon cancellation:

  • Your Premium access remains active until the end of the current paid billing period.
  • After expiry, your account automatically downgrades to the Free Tier. No data is deleted immediately; your boards are preserved in Firestore and you may export them before or after downgrade.
  • No partial-period refunds are issued. See our Refund Policy for full details.

Note: We do not issue refunds for unused subscription time. When you cancel, you retain Premium access until your plan expires, then seamlessly continue on the Free Tier.

4.5 Price Changes

We may change subscription prices with at least 30 days' notice. Price changes take effect at your next renewal. Continued use after a price change constitutes acceptance of the new price.

4.6 Failed Payments

If a payment fails, Paddle will retry according to its standard dunning schedule. If payment remains outstanding, your subscription may be suspended and your account downgraded to the Free Tier.

5. Acceptable Use

You agree not to use the Service to:

  • Violate any applicable law or regulation.
  • Transmit any content that is unlawful, harmful, threatening, abusive, harassing, defamatory, or otherwise objectionable.

  • Interfere with or disrupt the integrity or performance of the Service.
  • Reverse-engineer, decompile, or disassemble the Service except as permitted by applicable law.
  • Use the Service to store, share, or process sensitive personal data (e.g. financial account numbers, government IDs, health records) without appropriate safeguards.
  • Resell, sublicense, or commercially exploit the Service without our prior written consent.
