My Home privacy notice

Version 2026-10-23. This notice covers My Home accounts. The main Costwise privacy notice covers the public website.

Who is responsible

Stephen Evans trading as Costwise. Email: [email protected]. Business address: 11 Broadstone Crescent, Crowborough, TN6 2YL, United Kingdom.

What we use and why

We use your email address, account ID, sign-in/session information and home entries to provide the service you request. Home names, task dates, notes, project amounts, savings plans and quotes are information you choose to enter. You do not need to provide a home address. Our contractual basis covers running your account, saving your entries and administering subscriptions. Security and limited diagnostic logs support our legitimate interests in protecting the service. Legally required financial records are kept to meet our legal obligations.

Service providers

Supabase stores account and notebook data in our London-region project and supplies authentication. Cloudflare hosts the website and processes account requests. Resend sends sign-in and service emails. Stripe handles payments, payment-method details, billing and fraud prevention; Costwise does not receive your full payment-card number. These providers may process support, security or delivery data internationally under their applicable data-protection arrangements. A London database region does not mean every service operation takes place in the UK.

Cookies and private entries

My Home uses essential, secure session cookies to keep you signed in. They are not advertising cookies. The example home stores fictional entries in your browser until you clear them. The private app does not run marketing analytics, send your notes to an AI service or automatically send your information to affiliate partners. Following a public cost-guide or partner link is a separate action under the relevant site's privacy notice.

Retention and deletion

Your notebook remains available after a trial or subscription ends so you can read and export it. We keep it until you delete your account or ask us to erase it; we will review inactive account retention as the service develops and give notice before any automatic removal. Account deletion removes the active notebook, account and associated membership record. It also removes the app's Stripe customer and cancels subscriptions. Stripe may retain invoices and transaction records for legal, accounting, fraud-prevention and dispute purposes.

Deleted data may remain in restricted provider backups until those backups expire under the provider's retention settings. It is not used as an active account; any recovery process must reapply deletion requests. We do not promise that backup copies vanish immediately. You can contact us for current retention information or a wider erasure request. We retain only records needed for an applicable legal obligation or dispute, and review them when that need ends.

Your choices and rights

You can correct entries, export your notebook and delete your account in Settings. You can also ask for access, correction, erasure, restriction or portability, and object to processing based on legitimate interests where applicable. Email [email protected]; we may need to confirm your identity and normally respond within one month. You may complain to the Information Commissioner's Office. We do not use your notebook for automated decisions with legal or similarly significant effects.

Contact and changes

Contact [email protected] about privacy, access or deletion. We will notify account holders of material changes to how their information is used. Please avoid putting sensitive personal information or other people's private details in notes unless necessary and lawful.
