FAQ

LensDay is an AI-powered self-reflection journal for Android. You write or speak a check-in; an AI coach generates a personalized reflective response and follow-up questions. Over time, the coach learns your patterns and adapts to what matters most to you.

LensDay is designed for growth-minded adults who value introspection and quiet, high-quality design. It is not therapy, medical advice, or crisis support — see section 8 of our Terms of Service for the full non-medical disclaimer.

After each check-in, LensDay sends your entry to an AI language model that generates a personalized reflection and follow-up questions. Over time, your coach builds a picture of your patterns and adapts its responses to what matters most to you.

Guided check-ins include AI-generated follow-up questions that go deeper into what you wrote. The coach asks 2 to 4 enrichment questions and gives a longer terminal reflection. Available on the free tier for the first 7 days (1 onboarding check-in + 6 guided daily check-ins) and unlimited on Premium.

Free-text check-ins are simpler — you write or record, and the coach responds. No follow-up questions. Available from Day 7 onward on the free tier (1 per day) and unlimited on Premium.

A check-in can be text, a photo, a video, or a voice recording — whichever feels most natural for what you want to say. You can combine them — for example, a photo plus a short text caption.

The four input types are available on the free tier during your first 7 days (1 onboarding check-in plus 6 guided daily check-ins). From Day 7 onward, the permanent free tier becomes text-only, with one text check-in per day. Premium and Founding Member subscribers keep all four input types, subject only to the fair-use bands described in section 7 of our Terms of Service.

Yes. Coach responses are always delivered as text first; you can also tap the Listen to coach button on any response to hear it played back in audio, using the coach voice you selected. Audio is generated on demand by an AI text-to-speech provider — see section 4 of our Privacy Policy for details.

Audio responses are available throughout the first 7 days on the free tier, and on every check-in for Premium and Founding Member subscribers. From Day 7 onward, the permanent free tier becomes text-only with no audio playback.

LensDay ships with 12 coach voices, split by tier:

• Free tier — 2 voices:
  • George (male)
  • Sarah (female)
• Premium and Founding Member — all 12 voices (the 2 free voices plus 10 additional voices):
  • Male — Wyatt, Daniel, Brian, Finley, Bill
  • Female — Matilda, Lily, Alice, Regina, Maisie

All 12 voices speak natively in the 5 supported languages (English, Spanish, French, German, Brazilian Portuguese). You can pick or change your voice from the Profile tab.

LensDay is currently Android only. An iOS version is planned for a future release.

You can review past check-ins that have already loaded into the app while offline, but creating a new check-in requires an active internet connection — the AI coaching response is generated by a remote model. The app is not designed for fully-offline use.

The free tier requires no payment and no credit card. Premium subscriptions are available within the app at the current pricing displayed at the time of purchase. We do not list prices on this page because we run pricing experiments and prefer to show you the exact price you would pay.

No, because we do not want a billing surprise to be part of your relationship with LensDay. Instead, the free tier is permanent — you can use it for as long as you like at no cost.

For the first 7 days, the free tier includes guided multimodal check-ins. From Day 7 onward, the free tier becomes text-only with one check-in per day, indefinitely. This is a permanent product feature, not a time-limited trial.

You only pay if and when you decide that Premium is worth it for you.

The Founding Member tier is a limited founding-rate annual subscription, capped at the first 500 subscribers. Founding-rate pricing applies for the lifetime of an uninterrupted subscription. See section 5.5 of our Terms of Service for the full conditions.

If the Founding Member option is no longer visible on the paywall in the app, the cap has been reached.

Subscriptions are billed by Google Play, so cancellation also happens through Google Play:

1. Open the Google Play Store app
2. Tap your profile picture (top right)
3. Payments & subscriptions → Subscriptions
4. Find LensDay → Cancel subscription

Cancellation takes effect at the end of your current billing period — you keep access to paid features until that date.

Refunds are handled by Google Play under their refund policy. We do not process refunds directly.

Yes. LensDay is hosted on European servers and is fully GDPR compliant. Your check-ins are processed by AI only to generate your coaching response — no human ever reads them. Your data is never sold or used for advertising.

For the full picture, see our Privacy Policy.

Only you. Your check-ins are sent to an AI provider to generate your coaching response, then stored securely in your private account. No LensDay team member can read your entries.

In Frankfurt, Germany (Supabase, region eu-central-1). This keeps your data inside the EU at rest, under GDPR jurisdiction.

Some AI providers may briefly process your check-ins on infrastructure located in the United States during the moment of generating a response, after which the response is returned to our EU-based storage. See section 4 of our Privacy Policy for the full processor list.

No. We have configured our AI providers (OpenAI, Anthropic, Google AI) to not use the requests we send them for training their general-purpose models. This is in addition to those providers’ contractual default not to use API-tier data for training.

In the app: tap Profile → Export Data. This generates a JSON file containing your profile, check-ins, coach responses, insights, and memory tags, which you can share through your phone’s standard share sheet. This is the in-app implementation of your GDPR Article 20 portability right.

When you request account deletion, your data enters a 30-day grace period. During this time you can reactivate your account by signing back in. After 30 days, all your data is permanently deleted from our servers.

The Account deletion page walks through both deletion paths (in-app + email) in full detail.

Yes. During onboarding you chose between Direct, Warm, and Observant. You can request a tone change by contacting support — a self-service tone picker is coming in a future update.

You can reach us at support@lensday.app or through the contact form on this site. We aim to respond within 2 business days.
