Capsule is an offline time-capsule app. The user writes a note and optionally attaches photos, videos or voice recordings captured with the device camera and microphone, then picks a future date and "seals" the capsule. The capsule stays locked until that date; when the date arrives the user breaks the seal in a short animated ritual and relives the memory. Distinctive feature: for each capsule the user chooses a reveal mode — "surprise" (even the opening date is hidden), "hint" (a vague seasonal hint such as "this winter") or "exact" (exact date and days remaining). Everything is fully offline. There is no account, no sign-in, no cloud and no server. All capsules, notes and media are stored only in the device's local storage (IndexedDB inside the app's own sandbox) and never leave the device. Uninstalling the app deletes everything permanently; there is nothing for us to delete on our side. Monetization: the app is free with an optional auto-renewing monthly subscription ("Capsule Premium") sold through Google Play Billing, which includes a free trial period. The free tier allows one active (unopened) capsule at a time; Premium removes that limit and unlocks a richer "golden" opening ritual. Purchases and subscription management are handled entirely by Google Play — we never see or store payment details. There are NO advertisements and no ad SDKs. Permissions used: camera and microphone (only while the user is actively recording a photo, video or voice note into a capsule; the recording is written straight into local storage), and internet access (used only for Google Play Billing and an optional remote configuration fetch — no user content is ever uploaded). The app is not directed at children.
