By accessing, registering for, or using Lettie, users agree to be bound by these Terms. Users represent and warrant they have legal capacity to enter into the Terms. If accepting on behalf of a company or legal entity, the user warrants authorisation to bind that entity.

2. Description of Service
Lettie provides an AI-powered WhatsApp chatbot service designed for UK-based landlords to offer to their tenants.
Service Scope
- Automated triage of tenant maintenance and property queries.
- Simple fixes and guidance for common property issues.
- Escalation to landlords via preferred contact methods where the AI cannot provide a suitable solution, there is danger or safety concern, professional attention is required, or the issue is beyond automated assistance scope.
Tenant access is available 24/7. Landlord support is available during business hours (09:00–17:00 UK time, Monday–Friday, excluding UK bank holidays).
Important Limitations
- AI may not always provide accurate, complete, or appropriate advice.
- The Service is not a substitute for professional property management, maintenance services, or emergency services.
- Tenants must call 999 in life-threatening situations.
- For gas leaks, electrical hazards, flooding, fire risks, or structural dangers, tenants should evacuate if necessary and contact emergency services and/or relevant professionals immediately.
3. Tenant Data and Consent Requirements
Mandatory consent is required before onboarding any tenant. Users must obtain explicit, informed consent for Lettie to process personal data, contact tenants via WhatsApp, and store/process communications.
User Responsibilities
Users are solely responsible for obtaining valid consent, ensuring transparency, keeping records, and informing tenants of their data rights.
Roles
Users are the Data Controller; Lettie is the Data Processor acting only on lawful instructions in accordance with applicable law.
Verification and Objections
If a tenant objects or requests removal, Lettie may investigate, suspend access, remove data if consent cannot be verified, and terminate accounts for systematic failures.
Tenant Rights
Tenants may exercise rights via the Lettie website or through the user; responses will follow UK GDPR requirements.

23. Insurance and Liability
23.1 Landlord Responsibility for Insurance
Users remain solely responsible for maintaining appropriate insurance in relation to any property managed or referenced through Lettie, including buildings, contents, and property-owners' liability insurance. Lettie does not provide or arrange insurance of any kind and does not replace any landlord/property insurance requirement.
23.2 Nature of the Service
Lettie is a digital communication and maintenance-triage platform that assists landlords in managing tenant repair/maintenance issues. Lettie does not conduct physical inspections, perform repairs, or act as an insurer, letting agent, or contractor. Actions taken based on reports, summaries, or automated communications generated by Lettie are the user's sole responsibility.
23.3 Limitation of Liability (Supplement to Section 15)
To the fullest extent permitted by law, Lettie and its affiliates are not liable for any indirect, consequential, or incidental loss or damage (including loss of rent, profit, or reputation) arising from Service use, except where such loss arises directly from Lettie's proven negligence or wilful misconduct. Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, fraud, or any liability that cannot lawfully be excluded under UK law.
23.4 Contractor and Third-Party Work
Where maintenance or repair work is arranged by or through the user, any contract for such work is strictly between the user and the contractor. Lettie accepts no liability for the performance, timing, cost, or quality of third-party work or services arranged following a tenant report.
By using Lettie, users confirm they have read, understood, and agree to be bound by these Terms as updated from time to time.
