Article 1. Introduction

SeeYouSomeday (Japanese name: あなたへ) is an app for writing a letter written for a future date, so that it opens on that day inside the recipient's iPhone. The app is provided by BucksBox.ai (referred to below as "we" or "us").

We regard your privacy as our highest priority. The app is designed so that the contents of your letters are never sent to our servers or to any cloud service of ours; everything is handled only on your iPhone and on the iPhone of the person you hand the letter to. This policy explains, as plainly as we can, what information the app handles, for what purpose, and how it is protected.

Article 2. Our basic approach

The app does not collect your information. The contents of a letter are stored only on your device and on the device of the person you hand it to, and no third party, including us, can read them. No account or login is required. The app shows no advertising and gathers no usage analytics. We operate no server that stores letters. Letters change hands only through your own action: when the recipient is next to you, directly from app to app (over a nearby-device connection); when they are far away, by passing the file via a messaging app or email. In every case, nothing passes through our servers or any storage on the internet.

Article 3. Information the app handles

Everything the app handles is created or configured by you, and all of it is stored on the device. Specifically:

(1) Letter contents The body text, any attached photos, voice recordings and videos, the recipient's name, and the opening date. A letter to be handed over is converted (encrypted) into a file that can be received only on the recipient's device.

(2) Address book entries The display name of each registered recipient and the public information used to seal letters to them (the shareable part of an encryption key). Only these two items are exchanged — either through the direct device-to-device transfer when the recipient is next to you, or through the message you yourself send when they are far away — and we never handle their contacts or phone number.

(3) Information used for identity checks The keys used to confirm your identity when opening a letter are stored in the iPhone's secure storage (the keychain). They are synchronized through Apple's iCloud Keychain so that they carry over when you change devices. The optional 4-digit passcode is never stored as-is; only an irreversible digest (hash) of it is kept.

(4) App settings The notification time, your display name, and whether the first-run guide has been shown.

(5) Purchase status Whether the paid feature (Pro) has been purchased is confirmed through Apple's own mechanism. We never receive your name, card number, or any other payment details.

Article 4. Where information is stored and how it is protected

All of the app's information is stored only on the device. It is never sent to our servers or cloud. Storage uses the database and file-protection features built into iOS, and the device's standard encryption together with per-app isolation (sandboxing) keeps other apps from accessing it.

A received letter remains sealed (encrypted) until its opening date, and the app itself does not display its contents before then.

If you have iCloud Backup or computer backups enabled, the app's data may be included in those backups through standard iOS behavior. This depends on your own settings, and we recommend keeping backups enabled so that your letters carry over when you change devices.

Article 5. Network connections

The app makes exactly one kind of connection to the internet. When a letter is opened, the app asks several trusted servers (Apple, Cloudflare, Google) for the current time, in order to prevent the date from being falsified. This connection is encrypted (HTTPS), and the only thing obtained is the time. The contents of letters and your information are never transmitted. Beyond this, the app never sends information to the internet on its own.

Separately, when you use "Hand over in person," the app sends the sealed (encrypted) letter file directly to the recipient's nearby device. This is a short-range, direct connection over Wi-Fi or Bluetooth; it never passes through the internet, our servers, or any other storage. The app may ask for permission to access the local network for this feature, and that access is used only to hand a letter to a nearby device. The only thing sent is the letter file intended for the recipient you choose, and its contents can be opened only on that recipient's device.
