Lykka is built to keep what you write private. The short version: your memories stay on your phone. Our server tracks your subscription. That's all.
Who we are
Lykka is built and operated by Jesper Lodehed in the quiet of Sweden. Contact: lykka@lodehed.se. We are the data controller for the small amount of information described below.
What stays on your device
Everything you create in Lykka — text, photos (including EXIF data such as date and location), voice recordings and their transcripts — is stored locally in the app's container on your iPhone. The standard iCloud Backup picks it up if you have backup on. It is never on our servers and it is never logged by us.
Voice recordings are transcribed to text on your iPhone using Apple's built-in feature. The audio never leaves the phone.
What our servers store
To verify your subscription and count anonymous usage against your quotas we store:
- A random user id and your device's public key (Ed25519). The private key is generated on the device and never leaves it.
- Your subscription status, the original transaction id from Apple, and timestamps for start, renewal and cancellation.
- Per-month counters for the number of reflections, enrichments and affirmations you have used.
- Locale (sv or en) and app version.
- A log of Apple's subscription notifications, which is cleared automatically after 30 days.
We do not collect an email address, a name, a password, or any other identifier you would supply. You never sign in.
AI
When you ask Lykka to hand back a memory (a reflection or an affirmation), the memory text and language are sent through our server to Anthropic, which runs the language model. The processing happens in memory and is never stored on our side. Anthropic, as the provider, does not retain the content beyond what is described in their privacy policy.
Analytics
We use PostHog for anonymous event counters such as installed, reminder tapped and paywall shown. No content is sent — only counters and metadata (app version, iOS version, locale, days since install). The PostHog person id is the same random user id our server uses; it cannot be tied to you as a person.
Subscription
Subscriptions are handled entirely through Apple's App Store. We receive a signed receipt (JWS) from your device and from Apple's server, verify it, and store only the minimal information needed to know that you have access. We never see your card, your Apple ID, or your contact information.
Retention
The server record of your subscription is kept as long as the subscription is active. Per-month counters are kept for twelve months for simple troubleshooting and are then removed. The Apple webhook log is cleared automatically after 30 days.
The data inside the phone is yours. If you uninstall Lykka, it is gone.
Where we store it
Our servers and the small amount of metadata we keep sit inside the EU.
Your rights (GDPR)
What you write never reaches us, so there is no content for us to disclose, correct, or delete. On the server we keep only an anonymous user id and a few subscription records. If you want to know exactly what is in your record — or ask us to remove it — email lykka@lodehed.se with your anonymous user id (in the app's settings, under About). You may also complain to the Swedish Authority for Privacy Protection (IMY).
Children
Lykka is not directed at children under 13. We do not knowingly collect information about children.
Cookies
