Harmony

Privacy Notice

Last updated: 8 November 2026

1. Who is responsible for your data

Harmony is operated by LetsRead UAB (trading as “Harmony”), registered at V. Nagevičiaus St. 3, LT-08237 Vilnius, Lithuania. LetsRead UAB is the data controller for the personal data described in this notice — meaning we decide how and why your data is processed. Contact: info@ystl.ca.

2. What we collect and why

  • Account data — your name, email address, login credentials and profile photo, used to create and secure your account (legal basis: performance of our contract with you).
  • Profile and relationship data — the onboarding answers you give (such as conflict style and love language), your couple link, and the concerns, messages and live-session transcripts you choose to create, used to provide the advice and mediation features (legal basis: contract; for sensitive details you choose to share, your consent).
  • Support messages — anything you send us when you contact support, used to help you (legal basis: legitimate interests).
  • Usage and device data — basic telemetry, device identifiers and IP address, used for security, fraud prevention and improving the product (legal basis: legitimate interests).

Payment card details are collected and processed directly by our payment processor, Stripe — we never see or store your full card number.

3. How AI processing works

To generate advice and live mediation, the content you share is processed by AI models through our hosting and AI infrastructure providers. This processing happens only to provide the service to you and your linked partner. We do not sell your personal data, and we do not use your private conversations for advertising.

4. Who we share data with

  • Your linked partner — shared concerns, session summaries and couple memory are visible to the partner you linked with, by design.
  • Service providers / subprocessors — hosting, database, AI processing, analytics and support tooling providers who process data on our behalf under contract.
  • Payment processor (Stripe) — for the sale of subscriptions, payment processing, tax compliance and invoicing.
  • Professional advisers — such as lawyers and accountants, where needed.
  • Authorities — where we are required to do so by law.

5. International transfers

Some of our service providers are located outside the EU/EEA. Where your data is transferred internationally, we rely on appropriate safeguards such as EU Standard Contractual Clauses or adequacy decisions to protect it.

6. How long we keep data

We keep your personal data for as long as your account is active and as needed to provide the service. When you delete your account, your personal data is deleted or anonymised, except where we must keep limited records for legal, tax or accounting obligations. Shared couple history remains available to the remaining partner, with your personal identifiers removed.

7. Your rights

Under the GDPR you have the right to access, rectify or erase your personal data, to restrict or object to processing, to data portability, and to withdraw consent at any time (without affecting processing that already happened). You also have the right to lodge a complaint with your supervisory authority — in Lithuania, the State Data Protection Inspectorate (VDAI). We respond to rights requests within one month. To exercise any of these rights, email info@ystl.ca.

8. Security

We apply appropriate technical and organisational measures to protect your data, including encryption in transit, access controls, and row-level security so that each couple’s data is only accessible to the two linked accounts.

9. Cookies

Harmony uses essential cookies and local storage only — to keep you signed in and remember your session. We do not use advertising or third-party marketing cookies. You can clear these at any time in your browser settings, though signing in again will be required.

10. Changes and contact

If we update this notice, we will post the new version here and, for significant changes, let you know in the app. Questions about privacy: info@ystl.ca.
