Chercha Terms of Service

Version 1.2.2. Effective date: 1 October 2026. Please read them carefully: by creating an account and subscribing you accept these terms. If you do not agree, do not use Chercha.

1. Who we are

Chercha is a service of Smart Dynamic Systems LTD, a company registered in England and Wales under number 16430324, with its registered office at 66 Paul Street, London, England, EC2A 4NA (United Kingdom). Contact: support@getchercha.com (English) or ayuda@getchercha.com (Spanish). In these terms, “Chercha”, “we” or “our” means that company.

2. What Chercha is

Chercha is a subscription app for iPhone that teaches you the English people really speak in your region: expressions, phrases for everyday situations, local pronunciation and slang, with audio in the regional accent, a review, a widget and a daily notification. It is digital content for educational purposes. It is not an official course and does not award any qualification, certificate or recognised level.

3. Adults only (18+)

Chercha is only for people aged 18 or over. By creating an account, you confirm that you are 18 or older. The content includes colloquial, vulgar or offensive language as it is really used, which you only see if you turn it on. If we learn that a user is under 18, we will close their account and delete their data.

4. Your account

• You sign in with Sign in with Apple or with an anonymous account linked to your iPhone. You are responsible for what is done with your account.
• Your account is personal. You can use it on several devices; if we detect unusual use (for example, many devices on one account) we may ask you to review it.
• The AI welcome call is offered once per device.
• You can delete your account at any time in the app. Deleting your account does not cancel your Apple subscription: cancel it first in Settings > Cancel subscription.

5. Subscription, free trial and automatic renewal

• You need a subscription to use the app. There is no free plan.
• Annual plan: 7 days free, then US$49.99 a year in the US, £44.99 in the UK, €49.99 in the euro area, MXN 599 in Mexico, COP 119,900 in Colombia and US$34.99 in Argentina. In other countries, the price shown in the App Store.
• Monthly plan: US$9.99, £8.99 or €9.99 a month, with no free trial.
• The final price in your currency, including any applicable taxes, is the one shown on Apple’s payment sheet before you confirm.
• Automatic renewal: your subscription renews automatically at the end of each period at the current price unless you cancel at least 24 hours before it ends. If you cancel during the trial, you will not be charged.
• Reminders: we remind you in the app on day 5 and day 7 of the trial and, if you give us an email address, we write to you before the trial ends and before each annual renewal, with the price, the date and how to cancel.
• Cancelling: in Chercha, Settings > Cancel subscription, which opens Apple’s subscription management; or in iPhone Settings > your name > Subscriptions. If we show you an offer to stay, you can skip it with one tap.
• Payments and refunds: Apple charges you through your Apple ID. Chercha cannot refund Apple purchases: ask Apple from the app (Help > Request a refund) or at reportaproblem.apple.com.
• Founder price: if you subscribe at the launch price and the annual plan price later goes up, for as long as you keep your subscription without a break you receive a balance equal to the increase at each annual renewal (section 12). If you cancel and come back later, the current price applies.
• Offers: we may offer promotional prices (for example, to people about to cancel). Each offer shows its price, duration and conditions before you accept it. Long-standing subscribers get balance: the Loyal price from your third year (section 12). Counting that balance, a long-standing subscriber never pays more than a new one for the same plan.
• Price changes: if we change the price of your plan, Apple notifies you in advance and, where the law or Apple requires it, asks for your consent. If you do not consent, your subscription will not renew.

6. Right to cancel (cooling-off)

If you are a consumer in the UK or the European Union, you normally have 14 days to cancel a distance contract. Because Chercha gives you immediate access to digital content, when you start the trial or subscription we ask you to expressly agree to immediate access and to acknowledge that you thereby lose your right to cancel, to the extent the law allows. This does not affect your rights if the content is faulty (section 7) or any refund Apple grants under its own terms.

7. Faulty content

If you are a consumer in the UK, the Consumer Rights Act 2015 requires digital content to be of satisfactory quality, fit for purpose and as described. If it is not, you can ask us to repair or replace it and, if that is not possible, for a price reduction. Email support@getchercha.com. In other countries you have the equivalent rights under your local law.

8. The AI welcome call

• When you start, you can talk for a few minutes (10 at most) with a voice assistant that is an artificial intelligence, not a person. We tell you before the call and the assistant says so when it greets you.
• Before the call we ask for your permission to send your voice in real time to our AI voice provider and the language model it uses. The call is recorded: the recording, the text and its analysis are kept for 30 days by our provider and then deleted. See the privacy policy for details.
• At Chercha we only keep answers from fixed lists from the call to prepare your plan (for example, region, sector and level). At the end you see that profile and can change it.
• If you do not want to talk to the AI, or would rather the call is not kept, you can use the written form instead. The experience is the same.
• The AI can make mistakes. It does not give professional advice (legal, medical, immigration or financial). It does not charge you or start anything: you start the trial on the plan screen, through Apple’s payment sheet.

9. Chercha content

• Chercha’s expressions, explanations, audio, text and designs belong to us or our licensors. We give you a personal, non-exclusive, non-transferable and revocable licence to use them in the app while you have an active subscription, only for your personal, non-commercial learning.
• You can share an expression using the app’s share card. You may not copy the catalogue, scrape it, resell it or use it to train AI models.
• We use AI tools to prepare some of the content and the voices in the audio. It may contain mistakes or become outdated: if something doesn’t sound right, let us know with “Report a mistake” and we’ll look into it. Vulgar or offensive expressions are shown with their register so you know when not to use them; explaining them does not mean we endorse them.
• If the app links to or shows third-party content (for example, a source where an expression was heard), that content belongs to its owner and is subject to their terms.

10. Your content

• Personal dictionary, notes and your own audio: they remain yours. You give us a limited licence to store, display, sync and back them up, only to provide the service to you. You can export and delete them.
• Ideas box: governed by the Ideas Box Rules, which include a broader licence so we can use and build your ideas.
• Reports and support messages: we use them to fix content and to help you.
• Do not include sensitive data (health, documents, immigration status) or other people’s data in text or audio.

11. Acceptable use

You must not: use Chercha if you are under 18; share your account to avoid paying; misuse the AI call (for example, to make it do something else or to generate cost); reverse engineer, scrape or bypass security measures; upload content that is illegal, hateful, harassing or infringes others’ rights; or use the service commercially without our written permission.

12. Your balance, referral programme and ideas box

The “Gift a month to a friend” programme and the ideas box have their own conditions, which form part of these terms: Referral Programme Terms and Ideas Box Rules, at getchercha.com/en/referrals. What you earn through them, and by staying with Chercha, goes to “Your balance”, under these rules:

• What it is: time on your Chercha subscription, kept as days of your plan. The app shows it in days and in your currency (for example, “30 days of Chercha · US$9.99”): the amount is what those days are worth at your plan’s price in your country (the annual price divided by 365 or the monthly price divided by 30). It can only be used on your Chercha subscription. It cannot be bought, sold or transferred and has no cash value.
• Invitations and ideas: for each invitee who becomes a paying subscriber and for each idea of yours that we build, the price of one month of your plan (30 days of the monthly plan or 30.42 days of the annual plan). Together, up to the price of 3 months of your plan per calendar year.
• Active month: 2 days for each calendar month in which you meet your weekly goal (4 or more pieces seen) in at least 3 weeks. Weeks run from Monday to Sunday and count towards the month in which they start. Missing a week takes nothing away. Only with a paid subscription: the free trial does not count. The days are added as soon as you complete the third week.
• Anniversary: 7 days each time you complete a year of paid subscription (12 paid months, in a row or not). They are added with the payment that completes that year.
• Limit for active months and anniversaries: they are not added if your balance already reaches 90 days, which is what fits in one Apple extension. The app tells you.
• “Loyal” price (annual plan): from your third year, that is, from your second annual renewal, at each annual renewal you receive a balance equal to the difference between the annual plan price and the Loyal price. Today, in the US, that is a balance equivalent to US$10 (US$49.99 − US$39.99), which is 73 days of the annual plan at today’s prices; in other countries, the proportional amount in your currency. Apple lets us extend a subscription, but not lower its price for one person, and by at most 90 days at a time: you pay the annual price and your subscription lasts 73 days longer, so each year works out at about US$41.66, not US$39.99.
• Founder price (annual plan): if the annual plan price goes up, Apple charges you the new price and, for as long as you keep your subscription without a break, at each annual renewal you receive a balance equal to the increase (in days: 365 × increase ÷ new price). If both the Loyal price and the founder price apply to you, you receive the larger of the two, not both.
• Annual-plan balance: Loyal and founder balance can only be used on the annual plan. If you switch to the monthly plan, it waits, without expiring, until you return to the annual plan.
• How it is used: only by extending the renewal date of your Apple subscription. Apple allows at most 90 days at a time and twice every 365 days, and only with an active paid subscription: not during the free trial or without a subscription. If auto-renew is on, we apply it automatically a few days before your renewal; you can also use it whenever you like with “Use now”. The oldest balance is used first. Anything over 90 days waits for the next time. Apple sends you its own email each time, and an extension cannot be undone.
• Expiry: each part of your balance expires 12 months after you earn it, but that period only runs while you can use it: with an active paid subscription (not on the trial), when Apple allows an extension (no extension in progress and not already 2 in the last 365 days) and within the 90 days that would fit in the next extension. While you cannot use it because of Apple’s limits or because you do not have a subscription that allows it, the clock stops. We tell you 30 days before, in the app (you will see the date next to the amount in “Your balance”) and by email, if you gave us one. If auto-renew is on and an extension is still possible, we apply it before it expires.
• When else it is lost: when your account is deleted, by you or by us after 12 months without a subscription (section 13).
• Changes: what you have already earned keeps its value. If we change these rules, the change only applies to what you earn afterwards and we tell you in advance (section 15).

13. Suspension and termination

• You can stop using Chercha and delete your account at any time.
• We may suspend or close an account for serious or repeated breach of these terms, fraud, or where the law requires it. Except in urgent or fraud cases, we will warn you first and explain why.
• If you cancel your subscription, we keep your progress and dictionary for 12 months so you can come back without losing anything; after that we delete them. You can ask us to delete them sooner.
• If we stop providing the service, we will give you at least 30 days’ notice.

14. Liability

Nothing in these terms limits our liability for death or personal injury caused by negligence, for fraud, or for anything the law does not allow us to limit, nor your rights as a consumer. Otherwise, we are not responsible for losses that were not foreseeable or for business losses, because Chercha is for personal use.

15. Changes to these terms

If we change these terms in a way that affects you, we will tell you in the app and by email, if you gave us one, at least 30 days before the change applies. If you do not agree, you can cancel your subscription before that date. Minor changes or changes required by law may apply sooner. Previous versions are at getchercha.com/legal/history.

16. Apple

You download Chercha from the App Store, so Apple’s standard licensed application end user licence agreement (EULA) also applies. These terms are an agreement between you and Smart Dynamic Systems LTD, not Apple.

17. Governing law, courts and language

These terms are governed by the law of England and Wales. If you are a consumer living in another country, you keep the protection of the mandatory laws of your country and may bring a claim in its courts. These terms are available in English and Spanish with the same content; the version in the language in which you subscribed applies.

18. Contact and complaints
