ChartStreak Terms of Service
Last updated: 16 October 2026
These terms are the agreement between you and us about using ChartStreak. They are written to be read, not to be survived: where a rule can cost you something — a suspended account, a withheld payout, a subscription that renews — it is stated plainly and the reason is given. By creating an account or playing a round, you accept them.
1. Who you are agreeing with
ChartStreak is built and operated by Pavel Kastsiukou, an individual developer in Cyprus. Postal address: Andrea Zakou 11, 102, Mesa Geitonia 4000, Cyprus. Contact: [email protected].
How we handle personal data is a separate document: the Privacy Policy. It is part of this agreement.
2. What ChartStreak is — and what it is not
ChartStreak is an educational trading simulator. You are shown part of a price chart that has already happened and you predict where the price went next. The rest of the chart is held on our servers until you answer.
- No real trades. Nothing you do in ChartStreak buys, sells or holds any financial instrument. There is no brokerage account, no order, no position.
- Not investment advice. Nothing in the game — a chart, a score, a streak, a leaderboard, a hint — is a recommendation to do anything with real money. We are not a broker, a dealer, an exchange or an investment adviser, and we are not licensed as any of them.
- Historical market data may be imperfect. It comes from third-party providers, and it can be delayed, revised, incomplete or wrong. Past price movement predicts nothing about future price movement.
3. Who can use ChartStreak
You must be 18 or older. ChartStreak is not directed at children, and we do not knowingly let anyone under 18 hold an account.
You must also be allowed to use the service where you are. If your country or your circumstances make it unlawful for us to provide it to you, you may not use it.
4. Your account
- You get an account without asking. The first time you open the game we create a guest account tied to your device. It is yours, and it is as deletable as any other.
- Linking an e-mail address secures it. Until you do, the account lives with the device: clear your browser or lose the phone and it is gone. We cannot recover an unsecured account, because we have no way to tell that it was yours.
- One person, one account. Do not run several accounts, do not share yours, do not sell or transfer it, and do not play on someone else's behalf.
- Your nickname is generated by us. You cannot choose it; that keeps the leaderboards free of names that would need moderating.
- Keep your sign-in codes to yourself. Anyone with the code sent to your address can enter your account. You can end other sessions from your profile at any time.
5. Premium subscription
Premium is optional. Everything that decides a competitive result is free — see section 8.
| What it costs | USD 9.99 for 30 days. There is exactly one plan, and that is the price we set for it — we do not make one channel more expensive than another. Where an app store takes the payment, it sells at its own price points and in the currency of your country, so the amount it charges can differ; whichever channel you buy through shows you the exact figure before you confirm. |
|---|---|
| Free trial | Where an app store offers it, a new subscription starts with a 7-day free trial. When the trial ends, the store charges its price for the first period and the subscription renews automatically. You are not charged if you cancel in the store's subscription settings in time: in the App Store, at least 24 hours before the trial ends; in Google Play, at any time before it ends. The store decides who is eligible: a trial is offered once per store account. |
| What it unlocks | Unlimited training rounds and simulator runs, the round and simulator settings, intraday timeframes, the trade journal, your full play history and progress beyond the last seven days, and the chart indicators and markup tools. All of it or none of it — there are no partial tiers. |
| Who takes the money | Whoever you bought through. On iOS that is Apple, on Android Google, in a browser it is Paddle acting as merchant of record — which makes Paddle, not us, the seller for that transaction — and in Telegram it is a Telegram Wallet payment. We never see your card. |
| Renewal and cancellation | A subscription renews through the same channel that sold it, and is cancelled there: in the App Store or Google Play subscription settings, or through the link in the receipt Paddle sent you. Cancelling stops the next charge — in the App Store, provided you cancel at least 24 hours before the current period ends. The days you already paid for stay yours until they run out. |
| Refunds | Requested through the channel that took the payment, under its rules. We add no refund window of our own on top of those rules. When a refund goes through, we withdraw the premium days it paid for, in proportion to the amount returned and rounded in your favour. A cryptocurrency payment cannot be reversed on the blockchain — if something went wrong with one, write to us and we will sort it out by hand. |
6. Fair play
This section is the one that costs people accounts, so it is specific. While using ChartStreak you must not:
- let a program play for you — bots, scripts, macros, automated clients, device farms, or any other means of producing answers without a person making them;
- hold more than one account, or coordinate several accounts to cover more outcomes than one player could;
- interfere with the round — the timer, the client, the traffic between them, or anything else that changes how an answer is recorded;
- go after the part of the chart you have not been shown. The unrevealed data never leaves our servers before you answer, and trying to obtain it any other way is a breach of these terms, whether or not it works;
- reverse engineer, scrape or automate access to the app or our API beyond ordinary play;
- resell or sublicense access to the service, or use it to build a competing product;
- abuse other people through anything you can send us — support messages included.
Looking at charts elsewhere while you play is not cheating, and neither is being good at this. What is prohibited is not skill; it is substituting a machine for a player, or a crowd of accounts for a person.
7. What we may do about it
We run automated checks for the behaviour listed above. Where a check raises something, we may:
- put a hold on an account or on a payout while we look at it;
- disqualify an account from a competition period and reverse anything granted for it — reversals are recorded as entries in our ledger, not by erasing history;
- suspend or terminate the account for repeated or severe breaches.
What we will not do is act silently. If a decision goes against you, you will be told that it was made, and you can dispute it by writing to [email protected]. We answer support mail within five business days. We will not publish the detectors themselves: a published threshold is a threshold to play just under.
8. Competitive features
The daily challenge and the weekly standings have their own document — the Official Rules — which covers eligibility, how a day counts, the schedule and how results are settled. It applies to you if you take part, and it forms part of this agreement.
Two things belong here rather than there, because they are about this agreement: a subscription buys you no advantage in any competition — it grants no place, no share and no scoring benefit — and the server is the only scorer. Your device draws the chart and counts down for you; what is recorded is what our servers recorded, and that record decides the result.
9. Content and brand
- The app, the charts as we present them, the name ChartStreak and its marks are ours. You get a personal, non-exclusive, non-transferable right to use the app for its purpose — nothing more.
- Market data belongs to its providers. You may look at it inside the game; you may not extract or redistribute it.
- Result cards and shared links are yours to post anywhere you like. Sharing one publishes the chart and your result at that link.
- What you send us — a support message, a chart-of-the-day vote — you allow us to use to run and improve the service. We claim nothing beyond that.
10. Apple, Google and Telegram
ChartStreak is distributed through the App Store, Google Play and Telegram. None of them sponsors, endorses, administers or is a party to this agreement, and none of them is responsible for the app.
For the iOS app specifically: this agreement is between you and us alone; Apple has no obligation to provide any maintenance or support for it; if the app fails to conform to any warranty, you may tell Apple and Apple may refund the purchase price, and beyond that refund Apple has no other warranty obligation; any claim relating to the app is our responsibility, not Apple's; and Apple and its subsidiaries are third-party beneficiaries of this agreement and may enforce it against you.
11. The service changes, and sometimes it is unavailable
We add, change and remove features. We take the service down for maintenance, and sometimes it goes down without our permission. We do not promise uninterrupted availability, and a round lost to an outage is not a debt we owe you — though if an outage costs you something that matters, write to us and we will look at it.
12. Disclaimers and liability
The service is provided as it is. To the extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose and non-infringement, and we do not warrant that the service will be uninterrupted, error-free, or that market data will be accurate.
To the extent the law allows, our total liability to you for anything arising out of the service is limited to the greater of what you paid us in the twelve months before the claim, or $50.
Nothing here removes rights you have as a consumer. If the law where you live gives you rights that cannot be waived, they apply, and these terms are read subject to them.
13. Ending it
You can leave at any time, and you do not need us to do it: delete the account from your profile, or from chartstreak.app/account/delete. Deletion is final and you cannot sign back in, so collect anything owed to you first — the app will not let you delete the account while a payout is outstanding.
We may terminate your account for a breach of section 6, or if we have to stop providing the service to you at all. Sections 9, 10, 12 and 14 survive termination.
14. Governing law and disputes
These terms are governed by the laws of the Republic of Cyprus, and disputes go to the courts of the Republic of Cyprus. If you are a consumer in the European Union, this does not deprive you of the protection of the mandatory law of the country where you live, or of the right to bring a claim there.
Before going to court, please write to us — most of what looks like a dispute is a misunderstanding about a round, and we would rather fix it.
15. Changes to these terms
When these terms change, the new version is published at this address with a new date at the top. A material change is announced before it takes effect, by e-mail to the address linked to your account, if there is one, and at the top of this page, and a change never worsens a competition period that has already started — a rule you played under is the rule you are judged by.
