Terms of Use & Acceptable Use
Lock It
Package: com.appfactory.calculator
Terms version 4.0.8 · Effective September 20, 2026
Publisher: App Factory · support@afserver.dev
Companion: Privacy Policy · Account deletion
Short version: Use the app lawfully. The calculator opens a private vault via your secret equation.
Skip is allowed for a local vault only. Messages, groups, and Discover need a Google or email account.
We cannot recover a forgotten equation. The app is provided as-is. We may change or stop features, and we may
suspend or remove access — including kicking a user or a group — at any time, with or without notice.
Be respectful in Messages, groups, and Discover. CSAE and CSAM are banned.
1. Agreement
By accepting the Privacy Gate (first open) you agree to these Terms and the Privacy Policy.
If you do not agree, do not use the app. Continued use after we post an update to these Terms
is agreement to the update. We may change these Terms at any time. The version date at the top is current.
2. The product
- Calculator face + optional equation-locked private Vault
- Vault tools: Notes, Media, Camera, Keys/2FA, Phone Numbers, Invite, Weather, Secure, Settings, feedback
- Optional Messages (1:1 and groups) and Discover (people board + family-friendly circles; Freemium and Premium Pro)
- Live 1:1 video/voice in Messages: Freemium with Watch Bank credits; Premium Pro with weekly minutes then credits
- Optional encrypted cloud locker paid with Watch Bank credits or Encrypted Cloud ads (30-day GB blocks; unpaid files over remaining paid space are removed 2 days after a block ends)
- Tiers: Freemium, Premium Pro ($4.99/mo), Offline Vault (Google Play products)
The store listing and the Android home screen use the name Lock It
and a vault-door icon. This is a private vault with calculator entry —
not a calculator-only utility that hides a second product.
We may add, change, limit, or remove any feature, limit, price (through Google Play), storage,
credit, group, or cloud offering at any time. We do not promise the app will stay available,
stay the same, or keep any particular file, chat, group, or credit forever.
3. Eligibility
You must be 13+ (or older where your region requires a higher digital-consent age).
4. Account
First open: agree to these Terms, then Google, email, or Skip. Skip is a local Freemium vault only.
Messages, groups, Discover, and Encrypted Cloud need Google or email later.
You are responsible for keeping credentials and your equation secure. You may delete cloud account data in Settings
or via account-deletion.html.
5. Acceptable use
- Lawful personal or legitimate business privacy only
- Prohibited: illegal activity; child sexual abuse and exploitation (CSAE); child sexual abuse material (CSAM); sexual content involving minors; grooming; stalking/harassment; fraud; malware; spam; trafficking; threats
- Public Discover circles must stay family-friendly (no sex, porn, drugs, or gore in names, about text, or chat)
- Do not attempt to reverse-engineer server delivery for abuse
- Do not scrape Discover or spam friend requests
Use in-app Report and Block (separate buttons) for safety issues.
We review reports and take action when we have actual knowledge of a violation — including removing content,
kicking a user, unpublishing a card, or deleting a group. Confirmed CSAM is reported to
NCMEC Cybertip or your local child-safety authority.
Child-safety contact for Google Play: support@afserver.dev.
6. Suspension, kicks, and removal
Lock It is a private service. To the fullest extent the law allows, we may suspend, restrict, or terminate
your account, your access to Messages, groups, Discover, cloud locker, live calls, credits, or any other part
of the app at any time, for any reason or no reason, with or without notice, and without explaining
our decision to you. That includes removing you from a group, removing a group you created,
unpublishing a Discover card, deleting cloud files or extra circles, or refusing future access.
We are not required to give a warning, a refund (except where Google Play or the law requires one),
or a chance to appeal. Group creators may also remove members from their own circles under in-app controls.
Our rights here do not require us to monitor everything users post.
7. User content (Messages, groups & Discover)
- You own content you create; you grant us a limited license to host, deliver, moderate, and delete it as needed to run and protect the service
- Chat history is kept on each device after delivery; servers provide short-lived transfer, not a public archive
- Private groups are friends-only rooms of 3–12. Discover circles are opt-in public groups up to 500 and must stay family-friendly
- Group chat is text and emoji. Photos, video, and live calls stay 1:1
- Discover cards are public to other board users while published
- We may remove content that we believe violates these Terms, Play policy, or the law, or that we simply do not want on the service
- Paid credits and extra circles do not buy a pass for prohibited content
- Report abuse in-app or to support@afserver.dev. Never include your unlock equation
7a. Child safety
Lock It is 13+ and is not directed at children. We explicitly prohibit Child Sexual Abuse and Exploitation (CSAE)
and Child Sexual Abuse Material (CSAM), including grooming, sexualization of a minor, and trafficking of a child.
After actual knowledge of CSAM we remove it from our service as far as we can (transfer copies, Discover listings,
group metadata) and report confirmed CSAM to NCMEC or the relevant regional authority.
Google Play may reach the child-safety contact at support@afserver.dev.
8. Purchases, credits & ads
- Premium Pro ($4.99/mo, Play SKU unlimited) and Offline Vault ($9.99 lifetime) are sold via Google Play Billing. Optional Watch Bank credit packs are one-time Play purchases
- Restore purchases is available in Settings / paywall
- Refunds, cancellations, and billing disputes for Play purchases are handled by Google Play under Google’s terms. We do not override Play’s refund process
- Watch Bank credits are a limited in-app balance, not cash, not property, and not transferable outside the app. We may change earn rates, prices, caps, or what credits buy. Unused credits can be lost if we change or end the feature, if your account is closed, or if the app is discontinued — except where the law says otherwise
- Freemium may show a vault-home banner, occasional full-screen ads, app-open ads, and optional rewarded ads. There is no banner on the calculator face or while the vault is opening. Premium Pro and Offline Vault are ad-free
- Live video/voice: Freemium uses Watch Bank credits (1 credit = 1 minute of video or 3 minutes of voice). Premium Pro includes 90 minutes of video and 3 hours of voice each week (reset Monday 00:00 America/Los_Angeles); leftover credits add extra live time after that pool. Offline Vault has no live calls
9. Security, equation & lost vault
- Equation: stored as salted hash only. We never receive the equation in a form we can use to unlock your vault
- Vault: AES-GCM via PBKDF2 on this device
- We cannot recover a forgotten equation. Nobody at App Factory can reset it or open your vault for you
- If you forget the equation, lose the phone, uninstall without a backup you can open, fail a restore, or the vault will not decrypt, notes, keys, media, chats, camera items, cloud locker files, and other vault data can be gone forever
- Encrypted recovery (notes, keys, numbers, settings) still requires your equation. Camera photos stay on the original phone unless you copied them to the optional cloud locker
- Exporting a backup you can actually open is your job. The app is not a guaranteed backup service
To the fullest extent the law allows, we are not responsible for loss of the equation, loss of vault contents,
loss of chats or groups, loss of credits, loss of cloud files, or any other data loss, whether from user error,
device failure, OS update, our bugs, our changes to the app, or ending the service.
10. As-is · no warranty
THE APP AND ALL RELATED SERVICES ARE PROVIDED AS IS AND AS AVAILABLE,
WITH ALL FAULTS. We disclaim all warranties to the fullest extent the law allows, including implied warranties
of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that
encryption will stop a determined attacker, malware, a compromised phone, forensics, or legal process.
Calculator math is not warranted for engineering, medical, or other critical use.
Third-party services we use (for example Google Play, Firebase, Cloudflare, AdMob, weather providers)
have their own terms. We are not those companies and we do not warrant their service.
11. Limitation of liability
To the fullest extent the law allows, App Factory and its people are not liable for any indirect, incidental,
special, consequential, exemplary, or punitive damages, or for lost profits, lost data, lost vault contents,
lost credits, business interruption, or substitute services, even if we were told they were possible.
Our total liability for any claim related to the app is limited to the amount you paid us for Lock It
through Google Play in the three months before the claim, or zero if you paid nothing — except where
the law does not allow that cap (for example some liability for death, personal injury, or fraud).
Some places do not allow certain disclaimers. In those places, our liability is limited to the maximum
the law allows. These Terms do not take away rights that a consumer-protection law says you cannot waive.
12. Your responsibility
You agree to defend and hold App Factory harmless from claims that arise from your content, your groups,
your Discover card, or your use of the app in a way that breaks these Terms or the law, except to the
extent we caused the claim by our own willful misconduct.
13. Feedback
If you send ideas or Features & Fixes notes, we may use them without paying you or crediting you.
Do not send your equation.
14. General
- If a court strikes one part of these Terms, the rest still applies
- These Terms are the whole agreement for use of Lock It (along with the Privacy Policy and Google Play’s terms for purchases)
- A delay in enforcing a right is not a waiver
- You may not assign your account. We may assign these Terms
- Except where your local consumer law says otherwise, these Terms are governed by the laws of the United States, without regard to conflict-of-law rules
15. Contact
support@afserver.dev — never email your secret equation if you can avoid it.
