Your deal data is stored locally on your device and backed up to encrypted cloud storage on AWS in the UK. Data syncs automatically when you're signed in so you can pick up where you left off on any device.

Yes. All data is encrypted in transit with TLS 1.2+ and at rest with AES-256. The application is built following OWASP Top 10 security guidelines and is fully UK GDPR compliant. Your data is never shared with or sold to third parties.

All payments are processed securely through Stripe, which is PCI Level 1 certified — the highest level of payment security. We never see or store your card details. You can manage your subscription directly from the Settings page inside the app.

You get a full 5-day free trial with all Advanced features, and can analyse a single property. We take your card when you sign up but don't charge it during the trial — when the 5 days are up, your Advanced subscription starts automatically, unless you cancel before then from within the app. Either way your data is preserved, so you can pick up exactly where you left off.

Only the property and deal you're working on. Our AI features use OpenAI's business platform, where your data stays private: it's encrypted (AES-256 when stored, TLS 1.2+ when sent) and never used to train any AI models. We never send your account details, like the name and email you signed up with, and OpenAI's platform is SOC 2 Type 2 certified and handled under UK GDPR.

The calculator supports four UK property investment strategies: Fix & Flip (buy, renovate, sell), Buy-to-Let (single tenancy rental), BRRR (Buy, Refurb, Rent, Refinance), and HMO (House in Multiple Occupation — rent by the room). Each strategy has its own KPIs, cost breakdowns, and sensitivity analysis, and we're continuing to expand the toolkit — more strategies are planned for the future.

As you build your deal, AI helps with the parts that need judgement: refurb costs, sale price (GDV), rent, your deal plan, area insights and the final verdict. Each AI step sees the rest of your own deal, so its answers fit together. Your data stays private and secure throughout. Every AI request runs through our own secure servers on OpenAI's business platform, is encrypted (AES-256 when stored, TLS 1.2+ when sent), and is never used to train any AI models. We never share your account details, like the name and email you signed up with, and the platform is SOC 2 Type 2 certified and handled under UK GDPR.

The PropAI Deal Analyser doesn't run on consumer chat apps like ChatGPT, Claude, Gemini or Grok. Those apps can use what you type to improve their models, depending on your settings. Instead, we use OpenAI's business platform, built for companies that handle sensitive data. Your deal data is encrypted, kept private, and never used to train any AI models. The platform is SOC 2 Type 2 certified and handled under UK GDPR.
