Day Mate Privacy Policy

Last updated: 1 June 2026

Day Mate (the "App") provides voice conversation with an AI companion named "Youngja" designed for older adults. This policy explains what information the App processes and how.

1. Operator

• Name: Pickersoft (individual developer)
• Contact: pickerdotcom@gmail.com
• Support page: https://www.pickersoft.com/daymate_support_en.html

2. Information We Process

The App does not use accounts. We do not collect email addresses, phone numbers, or contacts.

Item	Handling	Stored at
Microphone audio	Briefly recorded on your device as an m4a file → sent to the App's server → forwarded to OpenAI Whisper for transcription → discarded immediately (neither we nor OpenAI retain the audio).	Transient
Transcribed text (your speech)	Held in server memory only for the duration of the conversation; discarded at session end.	Server memory (transient)
Profile (preferred address, interests, age band, speech preferences)	Shared by you during the first-run conversation; stored in the App's server database.	App server (persistent, deletable)
Daily conversation summary (one sentence)	Generated automatically when a conversation ends; used to give Youngja some continuity.	App server (persistent, deletable)
Install identifier (UUID)	Random anonymous ID generated on first launch. Used to link your profile across sessions.	Device + App server

The App does not collect: name, email, phone, contacts, location, photos, payment-instrument data (card numbers), the iOS advertising identifier (IDFA), or the Android advertising ID (AAID).

2-1. Subscription Payments

• Subscription purchases are handled entirely by the Apple App Store (on iOS) or Google Play Billing (on Android). The App never receives or stores card numbers or any other payment-instrument data.
• The App server tracks only your subscription status (active / expired) and expiry date, linked to your install identifier (UUID). Your Apple ID or Google account, the amount you paid, and your card details are not shared with the App.
• The same applies when a family member pays on your behalf via iPhone Family Sharing or Google Play family sharing — the App only sees whether a subscription is active.

3. Sub-processors

• Apple Inc. — iOS app distribution and subscription payment processing. Apple's privacy policy
• Google LLC — Android app distribution and subscription payment processing via Google Play. Google's privacy policy
• Anthropic, PBC — The App server forwards the text of your conversation to the Anthropic Claude API (claude-haiku-4-5) to generate Youngja's responses. Anthropic's privacy policy
• OpenAI, L.L.C. — The App server forwards your recorded audio (m4a) to the OpenAI Whisper API for transcription into text. The audio is discarded from our server's memory immediately after transcription, and under OpenAI's API data usage policy, OpenAI does not use API input for model training. OpenAI's privacy policy

4. Where Data Lives and How Long

• The App server runs on a private developer network located in the Republic of Korea.
• Profiles and daily summaries are retained until you delete them.
• Raw conversation transcripts are deleted immediately at session end and are never persisted.

5. Right to Deletion

Open Settings → Delete My Data in the App to wipe your profile and every stored summary in one step. Deletion is not reversible.

6. Analytics and Advertising

The App contains no analytics SDK, no advertising SDK, and no crash-reporting SDK.

7. Children

The App is intended for adults aged 50 and over. It is not directed to children under 14, and we do not knowingly collect data from children.

8. Safety Notice

The App does not provide medical, legal, or financial advice. In an emergency (chest pain, difficulty breathing, loss of consciousness), call your local emergency number immediately. If you are in emotional crisis, contact a local helpline (in the U.S., call or text 988 for the Suicide & Crisis Lifeline).

9. Changes

If this policy changes, the "Last updated" date at the top of this page will be revised, and material changes will be announced inside the App.
