Privacy Policy

DrySense AI is a London-based property assessment service operating at drysense.app. We provide free AI-powered damp and mould assessments for residential and commercial properties across London.

When you use DrySense AI we collect:

• Assessment data: property type, location (borough and postcode), problem description, severity rating, rooms affected, property age, floor level, tenure, treatment history
• Contact details: name and phone number (only when you choose to connect with a specialist)
• Photos: images you upload during your assessment
• Technical data: IP address, device type, browser type, session data
• Conversation data: the full text of your assessment conversation

We collect and process your data for the following purposes, each with a lawful basis under UK GDPR:

1. Service delivery (Legitimate Interest / Contract): To provide your free damp and mould assessment and deliver your results.
2. Specialist referral (Consent): To share your contact details with a vetted local specialist — only when you explicitly agree at the end of your assessment.
3. Service improvement (Legitimate Interest): To improve the accuracy and quality of our assessment tool.
4. Anonymised data analytics and commercial licensing (Legitimate Interest): We create anonymised, aggregated datasets from assessment data. No individual can be identified from this data. These datasets may be shared with or licensed to third parties including insurers, property managers, letting agencies and housing associations for research and analytics purposes. Examples include borough-level damp prevalence data, property age risk profiles and treatment cost benchmarks.

• Access the personal data we hold about you
• Request correction of inaccurate data

You may opt out of your assessment data being included in anonymised analytics datasets at any time by emailing drysense.ai@gmail.com with the subject “Analytics opt out” and your Assessment ID.
