Operator:Sole proprietor, British Columbia, Canada ("we")
Contact (privacy questions, access or deletion requests): career.dou@gmail.com
Service: Landlord AI at rentaihelper.com

1. Who this covers

Landlords with an account, tenants who send a maintenance request through a unit's QR code (no account), and contractors a landlord saves in their list.

2. Landlords tell their tenants

The landlord decides to use the service for a unit and is responsible for telling their tenants that an AI assistant, run by us with the providers listed below, processes the messages and photos tenants send, and for pointing them to this policy. The tenant page itself does not currently show this notice.

3. What we collect

Landlords: email address, password (stored by our login provider, not readable by us), unit names and details, and the maintenance requests for their units.
Tenants: what they type to the AI assistant, any photos they attach (up to 3 per request), the unit the request is for, and the time. The assistant is told not to ask for a name, phone number or exact street address unless needed, but a tenant may type them. Our servers also see technical data such as IP address, used for security and abuse limits.
Contractors: name, phone, email and trade, typed in by the landlord. In this version we only store them; we do not contact contractors.

We do not collect payment card details. Paid plans, when added, will use Stripe.

4. How we use it

To run the assistant and give the landlord a clear summary; to keep a history of requests per unit; to keep the service secure and prevent abuse; and to fix problems. We do not sell personal information and do not use it for advertising.

5. Who processes it for us

Supabase (database, login, private photo storage). Data region: Canada (Central).
OpenAI(the AI that reads tenant messages and writes the summary). Processed in the United States. According to OpenAI's published API terms, data sent through the API is not used to train its models by default, and may be kept for up to 30 days for abuse monitoring unless the law requires longer.
Vercel (website hosting).

Because these providers may be outside Canada, information may be stored or processed in other countries, including the United States, where local law applies.

We share information with the landlord of the unit concerned, and with authorities only when the law requires it.

6. Photos

Photos are stored in a private storage area and shown to the landlord through links that expire after one hour. Tenants should avoid photographing people or personal documents.

7. How long we keep it

We keep information while the landlord's account is active. After the account is closed we delete or anonymize it within 90 days, unless the law requires us to keep it. A person can ask for earlier deletion (section 8).

8. Your rights

You can ask to see, correct or delete personal information we hold about you, or withdraw consent, by emailing career.dou@gmail.com. We aim to reply within 30 days. Tenants and contractors may also ask the landlord, who controls the unit's records.

9. Security

Each landlord can only see their own data (database row-level security). Connections use HTTPS. No system is perfectly secure. If a breach creates a real risk of significant harm, we will notify affected people and the privacy regulator as required by law.

10. Children

The service is not meant for children.

11. Changes

We will update this page with a new date. For material changes we will email landlords with accounts.
