Privacy Policy

Last updated: February 24, 2026

1. Introduction

StackTidy ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our SaaS subscription detection and management service at stacktidy.com (the "Service").

The data controller for the Service is:

  • Company: Poverud IT
  • Organization number: 933 572 781
  • Registered address: Norway

By using our Service, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

2.1 Information You Provide

  • Account Information: Email address, name, and password when you create an account.
  • Subscription Data: Information about your SaaS subscriptions that you manually enter or import.
  • Payment Information: Billing details processed securely through our payment provider (Stripe). We do not store your full card details.
  • Communications: Information you provide when contacting support or using the AI chat assistant.

2.2 Information Collected Automatically

  • Usage Data: How you interact with our Service, features used, and actions taken. We maintain an activity log to provide features like team activity feeds.
  • Device Information: Browser type, operating system, and device identifiers.
  • Log Data: IP address, access times, and pages viewed.

2.3 Email Import Data

If you choose to forward subscription emails to your unique StackTidy address, or connect your Outlook account, we process emails matching subscription-related keywords such as receipts, invoices, renewals, payments, and trial notifications. Here is what that means in practice:

  • What we receive: Emails you forward to your unique StackTidy address, or emails matching subscription patterns from a connected Outlook account.
  • What we process: Email content matching subscription patterns is temporarily sent to our AI provider (OpenAI) to extract subscription details such as the app name, cost, billing cycle, and renewal date.
  • What we store: Email subject line, sender address, date, and the extracted subscription data. We do not store the email body itself.
  • What may be included: Because we use keyword-based filtering (e.g., "receipt", "invoice", "payment"), some personal purchase emails (such as Amazon or Apple receipts) may be processed if they match these patterns. We do not target personal correspondence.
  • Revocable: You can stop forwarding emails or disconnect your Outlook account at any time from Settings, which stops all scanning immediately.

2.4 Bank Statement Data

If you upload a bank statement CSV, we process transaction descriptions to detect recurring subscription charges. We store matched transactions (date, description, amount) as subscription records. The raw bank statement file is not retained after processing.

2.5 AI Chat Data

If you use the AI chat assistant, your messages and the assistant's responses are stored to maintain conversation continuity. Chat history can be viewed in Home and is deleted when you delete your account.

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our Service
  • Detect subscriptions from your email using AI-powered parsing

We use essential cookies required for authentication and core functionality. These cookies maintain your login session and preferences. They cannot be disabled while using the Service.

10. International Data Transfers

Your information may be transferred to and processed in countries other than your own, including the United States. We ensure appropriate safeguards are in place for all international transfers in compliance with GDPR Article 46:

  • EU-US Data Privacy Framework: Where applicable, we rely on the EU-US Data Privacy Framework for transfers to certified US-based providers.
  • Standard Contractual Clauses (SCCs): For transfers to US-based sub-processors not covered by the Data Privacy Framework, we have entered into Standard Contractual Clauses approved by the European Commission. This applies to our sub-processors including OpenAI, Vercel, Supabase (hosted on AWS us-east-1), Resend, and Upstash.
  • Stripe: Stripe offers EU data residency, and payment data is processed within the EU where possible. For any transfers outside the EU, Stripe relies on SCCs and the Data Privacy Framework.
