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