Warranties & receipts
Warranty Vault
Store warranties and receipts, and get a heads-up before cover expires — so you claim what's yours without digging through drawers.
Not out yet. Warranty Vault is built and in testing, and arrives on Google Play first. Join the waitlist and we'll email you the day it lands — one email, nothing else.
What Warranty Vault does
- Log what you own — name, category, price, purchase date, warranty length, return window, store, room, tags and notes.
- Told before it lapses — reminders before a warranty expires and before a return window closes, scheduled on your device.
- Photos stay private — receipts and product shots are copied into app-private storage, not added to your gallery and not visible to other apps.
- A 30-day Trash, so a mistaken delete is recoverable.
- An insurance-ready PDF or CSV inventory report, made on your phone.
- Optional app lock and encrypted Google Drive backup — both off until you turn them on.
Category warranty lengths are common defaults you can edit. The app's reminders do not create, extend or prove any warranty or return right.
The same promise as every Coffer app
What you record lives in an encrypted database on your own device. There is no account to create, no analytics watching you, and no server of ours holding a copy — so there is nothing for us to leak, sell or lose. Export your data whenever you like; nothing you have already written down disappears if you stop paying.
Warranty Vault questions
Do I need an account to use Warranty Vault?
No. Open Warranty Vault and start — there is no sign-up, no email address and no password. Your identity is your business, and the app works without it.
Where does Warranty Vault store my data?
In an encrypted database on your own phone. There is no server of ours holding a copy, so there is nothing for us to leak, sell or lose — and you can export your records whenever you like.
Does Warranty Vault have ads or tracking?
No. There are no advertising networks, no analytics SDKs and no third-party tags in any Coffer app.
Is Warranty Vault free?
Warranty Vault has a genuinely useful free core. One Coffer subscription unlocks the extras across every Coffer app instead of charging per app, and cancelling never takes away anything you have already recorded.
When can I download Warranty Vault?
Warranty Vault is built and in testing, and arrives on Google Play first. Join the waitlist and we will email you the day it lands — one email, nothing else.
