Terms of Service
These terms govern your use of the Crypto Alerts & Alarms mobile app on
Android and iPhone (store id com.appsfromzero.sentinel on both) and this website, operated by
Apps From Zero (“we”, “us”). Installing or using the
app means you accept them. If you do not, do not use the app.
The one thing to take away. This app tells you about prices. It is not financial advice, it does not trade, and an alert can be late or fail to arrive — a phone can be offline, a push service can be delayed, an exchange feed can stall, and a battery optimiser can hold a notification back. Do not build a position you cannot afford to hold on the assumption that an alert will reach you.
1. What the service is
Crypto Alerts & Alarms lets you set price alerts on cryptocurrency trading pairs from Binance, Coinbase, Kraken, Bybit and KuCoin, and — on the Degen plan — on tokens on the Solana network. When a price crosses the level you set, we try to reach you by push notification, by an alarm on your phone — full-screen on Android, a lock-screen alarm tone on iPhone — or by Telegram, according to what you chose.
Your alerts are evaluated on our servers, not on your phone. That is what lets them fire while the app is closed, and why they survive a change of device.
The app does not trade. It never connects to an exchange account, never asks for an API key, and has no ability to place, modify or cancel an order. It holds no funds and contains no wallet.
2. Your account
You do not have to sign up to use the app. On first launch it creates an anonymous account for your device, and you can arm alerts immediately. You may connect an email address and password, or Google or Apple Sign-In, at any time; doing so adds credentials to the account you already have, so nothing is migrated and nothing is lost.
An account you have not connected belongs to that one phone. The key proving the device owns it is stored on the device, and on Android it is deliberately kept out of backup. So if you lose, wipe or replace the phone — or uninstall the app — you may have no way back into that account, and we have no way to identify you as its owner. Do not rely on a backup to carry it. Connect an email, Google or Apple account before that matters to you. Your account id is shown in Settings › Privacy.
Whether or not you connect credentials, you agree to:
- give an email address you actually control, if you provide one — it is how we reach you about billing, refunds and security;
- keep your password to yourself and not share your account;
- be at least 16 years old, or the age of digital consent where you live if that is higher;
- tell us promptly if you believe someone else has access to your account.
There is no password reset in the app yet. If you connect an account with an email and a password, keep that password somewhere safe — this is why the app asks you to type it twice. If you are locked out, email us and we will help you recover or delete the account. Signing in with Google or Apple avoids the problem entirely.
What we do with your data is set out in the Privacy Policy, which forms part of these terms.
3. Acceptable use
Do not:
- use the app for anything unlawful, or in a way that breaks the rules of a market or exchange you participate in;
- attempt to access another person's account, or any part of our systems you have not been given access to;
- scrape, resell or redistribute the market data the app shows you, or use the app to build a competing service;
- automate, overload or attack the service, or work around its limits (including alert ceilings and paid-feature gates);
- reverse-engineer the app except where that right cannot lawfully be excluded.
We may suspend or close an account that does any of this. Where it is reasonable to do so, we will tell you why first.
4. Subscriptions, auto-renewal and trials
The app is free to install and free to use at a basic level. Two optional subscriptions — Pro and Degen — unlock more active alerts and more features; Degen includes everything Pro does. Each is sold weekly, monthly or yearly. The current price in your own currency is shown in the app before you buy, and that price is what governs.
- Purchases go through the store you installed from — Google Play on Android, the App Store on iPhone. We never handle your payment details, and that store's own terms apply to the transaction alongside these.
- Subscriptions renew automatically at the end of each period, at the then-current price, until you cancel. The store charges you within 24 hours of the period ending.
- Free trials, where offered, run for the length the store states, and the store decides whether you are eligible. One trial per person, across both plans — Google Play counts eligibility per app, the App Store counts it per subscription group, and Pro and Degen sit in a single group, so taking a trial on one plan uses up your eligibility for the other either way. A trial converts into a paid subscription unless you cancel before it ends.
- Changing plan is done in the app, or in Google Play or the App Store. The store prorates or credits the time you have already paid for, under its own rules.
5. Cancelling
Cancel at any time, from Manage subscription inside the app or from your subscription settings in the store that sold it — Google Play, or the App Store on iPhone. Cancelling stops the next charge; it is not a refund of the period you are in. You keep the paid features until the end of the period you have already paid for, and after that the account reverts to the free tier.
Your alerts are not deleted when a subscription ends. Alerts above the free ceiling, and ones using a paid delivery channel, stop being active until you are back under the limit or subscribe again.
6. Refunds
- Whoever took the payment issues the refund, so the route depends on the store. The app shows you the right one.
- On Google Play, the store's own refund window — generally 48 hours from purchase — is self-service and the fastest route. Outside that window Google hands the decision to us: write to support@appsfromzero.com and we will consider it on the facts. Refunds beyond the statutory minimum are at our discretion, and are granted through Google, since Google holds the payment.
- On the App Store, Apple decides. Apple reviews every refund request itself — we cannot issue one and we cannot speed one up. Ask Apple at reportaproblem.apple.com. If Apple turns you down, write to us and we will put your case to Apple. We usually reply within a day.
- A refund ends your access immediately, not at the end of the period.
- Nothing here limits any statutory right of withdrawal or cancellation you have under your local consumer law.
7. Price changes
We may change subscription prices. An existing subscriber is notified in advance by the store, and a price rise will not take effect for you until you have had the chance to accept it or cancel. Continuing after that is acceptance. Google Play's rules require this. The App Store would let some increases continue automatically instead, and we are choosing not to rely on that — the promise above is ours, and it applies wherever you bought.
8. Alerts are best-effort
We work hard at this — it is the whole product — but we cannot and do not guarantee that any particular alert will be delivered, or delivered at a particular time. Delivery depends on things outside our control, including:
- your device being powered on and able to reach the internet;
- Google's push infrastructure, and its own delivery timing;
- Android battery optimisation, Doze mode and manufacturer power managers, which can hold a notification back for minutes or longer;
- your notification, alarm and Do Not Disturb settings, which you control;
- exchange and on-chain data feeds being available and accurate;
- our own servers, which are not perfect either.
Markets can also move through your level and back again faster than any alert can travel. Set your expectations accordingly, and do not rely on an alert as the only thing standing between you and a loss.
9. Market data
Prices come from third-party exchanges and public on-chain sources. They may be delayed, rounded, briefly wrong, or unavailable. They are provided for information and are not an offer or a quotation. A price shown in the app may not match the price at which you could actually transact.
10. On-chain tokens carry extra risk
Solana tokens are permissionless: anyone can create one, name it anything, and copy an existing project's ticker and artwork. Many have almost no liquidity, a handful of holders, or a pool that can be drained. Some are built to be worthless.
The app shows warnings that name a specific reason — low liquidity, few holders, a newly opened pool — and it identifies a token by its mint address rather than its ticker, so two tokens with the same name cannot be confused. There is deliberately no trust score, no safety rating and no verification tick.
The absence of a warning is not a statement that a token is safe. We never make that claim and you must not read one into the app. Verify any mint address independently before acting on anything.
11. No financial advice
Nothing in the app or on this website is financial, investment, tax or legal advice, a recommendation, or a solicitation to buy or sell anything. We are not a broker, a dealer, an exchange or an investment adviser, and no part of the service is personalised to your circumstances. Every trading and investment decision you make is yours alone, and so is the outcome. Crypto assets are volatile and you can lose everything you put in.
12. Intellectual property
The app, this website, their design and their content are ours or our licensors'. You get a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you control, for your own purposes, while these terms are in force. Exchange names, logos and token artwork belong to their respective owners and appear for identification only — we are not affiliated with, endorsed by or sponsored by Binance, Coinbase, Kraken, Bybit, KuCoin, Solana, Jupiter, Google or Telegram.
13. Availability and changes to the app
We may change, add or remove features, and we may take the service down for maintenance. We will avoid removing something you are paying for without notice; if we remove a paid feature materially and you are mid-period, contact us and we will sort out a fair outcome. We may also discontinue the service entirely, in which case we will give reasonable notice and stop charging.
14. Termination and deletion
- You can leave at any time. Delete your account from Settings › Privacy › Delete account, or email us. This removes your account, your alerts and your notification history — see the Privacy Policy for exactly what goes.
- Uninstalling is not deleting. It clears the app from the phone and leaves your account and alerts in place — but if you never connected an email, Google or Apple account, it also loses your access to them, for the reason given in section 2.
- Deleting your account does not cancel your subscription — that is a contract with Google Play or the App Store. Cancel it in the store that sold it first, or you may keep being charged.
- We may suspend or terminate an account that breaches these terms. Where we do so without cause, any unused paid period will be refunded pro rata.
15. Disclaimer of warranties
To the fullest extent the law allows, the app and the website are provided “as is” and “as available”, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the service will be uninterrupted, timely, secure or error-free, or that any alert will be delivered.
16. Limitation of liability
To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive damages, nor for any trading loss, missed opportunity, lost profit or lost data, arising from your use of — or inability to use — the app, including any alert that was late, wrong or never arrived.
Where liability cannot be excluded, our total liability to you for all claims is limited to the greater of the amount you paid us in the twelve months before the claim arose, or US $50.
Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited. If you are a consumer, you keep every right your local law gives you, and nothing here overrides it.
17. Third parties and app stores
The app is distributed through Google Play and the App Store, and each store's terms apply as well as these. Neither Google nor Apple is a party to these terms, and neither has any responsibility for the app.
For the App Store specifically. These terms are between you and us, not with Apple. Apple has no obligation to furnish any maintenance or support for the app, and no warranty obligation of any kind. Apple is not responsible for addressing any claim you have about the app — including product liability, any failure to conform to a legal requirement, and any claim arising under consumer protection or privacy law — and any such claim is ours to answer rather than Apple's. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you as a user of the app.
The rest of what Apple requires us to say. Your licence to the app is non-transferable, and limited to Apple-branded devices that you own or control, under the Usage Rules in Apple's Media Services Terms. If the app fails to conform to any warranty, you may tell Apple, and Apple will refund what you paid for it — that is the whole of Apple's warranty obligation, and anything beyond it is ours. If someone claims the app infringes their intellectual property, answering that claim is ours as well. You must keep to any third-party terms that apply to your use of the app. And you confirm that you are not located in a country subject to a US Government embargo or designated by the US Government as supporting terrorism, and that you are not on any US Government list of prohibited or restricted parties.
Services the app relies on — Google Play Billing, the App Store, Firebase, RevenueCat, PostHog, Singular, Telegram, and the exchanges and on-chain data sources — operate under their own terms, and we are not responsible for their acts or omissions.
18. Changes to these terms
We may update these terms. The current version always lives at this URL, which is the one the app links to. For a material change we will update the date below and note it in the release notes; continuing to use the app after that is acceptance. If you do not accept a change, stop using the app and cancel any subscription.
19. Governing law
These terms are governed by the laws of the jurisdiction in which Apps From Zero is established, and disputes will be heard by the courts there. If you are a consumer, this does not deprive you of the protection of the mandatory laws of your own country of residence, or of the right to bring proceedings in your local courts. If any provision here is unenforceable, the rest stands.
