Booster is a mobile phone optimization app that combines storage cleaning, performance boosting, and battery management tools into a single recurring subscription. Unlike a one-time purchase, Booster charges you monthly or annually and renews automatically each billing cycle unless you cancel. For Malaysian users, this matters because the subscription continues to charge your card until you actively stop it, regardless of how often you actually open the app.
When you subscribe to Booster, you are not buying the app itself. You are paying for continuous access to premium optimization features. The service is delivered through the Booster app on your phone, but the billing relationship runs through one of three platforms: your web account at booster.io, Apple App Store, or Google Play Store.
Booster offers tiered subscription plans. Published examples show pricing ranging from approximately RM472 per month for basic access up to RM944 per month for premium tier plans with enhanced feature multipliers. The exact Malaysian pricing depends on which app store or web portal you used when you subscribed. Regardless of the tier you selected, the mechanism is the same: your payment method is charged on a fixed date each month or year, and the subscription auto-renews unless you cancel before that billing date arrives.
This automatic renewal structure is common in digital subscriptions, but it creates a critical window for cancellation. If you cancel on the day after your billing date, you have already paid for another full month or year. Yafee recommends recording your exact renewal date the moment you notice an unwanted charge, because this date controls when your cancellation takes effect.
Booster publishes its subscription terms across multiple websites: booster.io, booster.club, and the official help centre at help.booster.me. Support is available Monday to Friday, 10:00 AM to 6:00 PM JST, which translates to 9:00 AM to 5:00 PM MYT (Malaysian Standard Time) for most of the year. A live chat option exists during those hours, but no direct phone number is publicly listed. This fragmented support structure means you should gather all your documentation before contacting them, and you should expect potential language barriers when communicating outside business hours.
Your right to cancel a subscription is protected by the Consumer Protection Act 1999 (CPA 1999) of Malaysia, which is enforced by the Ministry of Domestic Trade and Consumer Affairs (MDTCA). Under this law, you have the statutory right to cancel any distance contract (including digital subscriptions sold online) within 14 days of entering into the agreement, without penalty or justification. This is known as your cooling-off period.
The Consumer Protection Act 1999 gives you three core protections when cancelling Booster:
If you cancel outside the 14-day cooling-off period, you may still cancel future charges, but you will not receive a refund for the current billing period unless Booster has breached its contract or committed an unfair practice. Booster's published terms state that cancellation stops future billing while access continues until the end of your paid period, which is a consumer-friendly arrangement.
If Booster refuses to cancel your subscription or continues charging you after cancellation, you can lodge a complaint with the Malaysian Consumer Tribunal or escalate to the MDTCA. Yafee has seen many cases where documentation of your cancellation request becomes critical evidence in such disputes, so always retain proof of every step you take.
Under the CPA 1999, Booster must acknowledge and process your cancellation request within a reasonable timeframe, typically within 5 to 10 business days. They must also confirm in writing that your subscription is cancelled and that no further charges will occur. If they fail to do so, they are in breach of consumer protection law. Yafee recommends sending your cancellation request via email or in-app chat so you have a timestamped record of your request and their response.
The method you use to cancel depends on where you subscribed, because payment control lies with that platform, not necessarily with Booster itself. Cancelling in the wrong place may leave your subscription active and your card continuing to be charged.
If you subscribed directly on the Booster website (booster.io or booster.club), this is the most direct cancellation route. Follow these steps:
If you subscribed to Booster through the Apple App Store on your iPhone or iPad, Apple controls the billing, not Booster. You must cancel through Apple's system. Here is how:
If you subscribed to Booster through Google Play Store on your Android phone, Google manages the billing. Cancellation must happen in Google Play, not on the Booster website. Follow these steps:
Cancellation does not mean immediate access loss. Booster's published terms confirm that you retain full access to all premium features until your current billing period ends. After that date, your account converts to free or inactive status, and you no longer have access to paid optimization tools.
Once you cancel, your timeline works like this. Your subscription status changes to "Cancelled" or "Expiring" in your account settings. You continue to pay for the current month or year (unless you cancelled within the 14-day cooling-off period). You retain full premium access throughout that final paid period. On your final billing date (which Booster clearly displays), your access expires. After that date, you can no longer use premium features, though you may retain the app on your phone in a free or trial state. You will not be charged after the final billing date unless you resubscribe.
Many users worry they will lose their data after cancellation. Booster does not delete your saved settings or app history when you cancel, so any custom configurations you have created remain accessible if you ever resubscribe. However, you lose access to the optimization tools themselves once the paid period ends.
Under the Consumer Protection Act 1999, you are entitled to a refund if you cancel within the 14-day cooling-off period, provided you have not substantially consumed the service. If you cancel outside the cooling-off period, Booster is not obligated to refund your current month or year of payment. However, if Booster charges you after your cancellation date, this is a breach of contract and consumer law, and you must immediately request a refund and escalate to the Malaysian Consumer Tribunal if necessary.
If you notice a charge on your card after the cancellation date, contact Booster's support at help.booster.me within 5 days of the erroneous charge. Provide your cancellation confirmation screenshot and the evidence of the unexpected charge. Request an immediate refund. If Booster does not respond within 10 business days, file a complaint with your bank or credit card issuer and with the MDTCA. Yafee has supported consumers through this exact scenario, and documentation is your strongest tool.
Understanding Booster's pricing helps you decide whether to cancel or identify whether you have been charged the wrong amount.
| Plan tier | Approximate monthly cost (RM) | Approximate annual cost (RM) | Key features | Auto-renews? |
|---|---|---|---|---|
| Basic Silver | RM472 | RM5,664 | Storage cleaning, basic performance boost | Yes, monthly |
| Standard Gold | RM944 | RM11,328 | Enhanced battery tools, priority support | Yes, monthly |
| Premium Platinum | RM1,416 | RM16,992 | All features plus reward multiplier scaling | Yes, monthly |
| Free trial | Free for 7 days | N/A | Full premium access, converts to paid tier on day 8 | Yes, if not cancelled by day 7 |
Prices are approximate and may vary by currency conversion or regional promotion. Always verify your actual plan and price in your account settings before cancelling, as you may have negotiated a discount or enrolled in a limited-time offer. If your charge does not match the published pricing, this may indicate a regional pricing adjustment, a currency exchange markup, or a billing error. Contact Booster support with a screenshot of your last charge and a request for clarification.
Cancellation is straightforward if you follow the correct platform and method, but users often stumble on preventable errors that delay or derail their cancellation. Here are the mistakes Yafee sees most often, and how to avoid them.
The most frequent error is cancelling through the Booster website when your subscription is controlled by Apple App Store or Google Play. This creates a false impression that you have cancelled, when in reality your subscription remains active and continues to charge. Always verify exactly which platform processed your original subscription. Check your banking app or email receipt from the time you subscribed. The merchant name on your card statement will tell you: "Apple", "Google", or "Booster" directly. Cancel only on that platform.
If you cancel after your billing date has passed, you have already been charged for another full month or year. Booster's terms state that future billing stops after cancellation, but they cannot refund charges already applied. To avoid this, mark your renewal date on your calendar and cancel at least 2 days before that date. Yafee recommends setting a phone reminder 3 days before your renewal date so you do not miss the window.
Many users cancel successfully but then fail to save the confirmation page or email. If Booster later charges you by mistake (or claims you never cancelled), you have no proof to back your claim. Screenshot the cancellation confirmation immediately and forward the confirmation email to yourself or save it in a dedicated folder. This evidence is your legal protection under the Consumer Protection Act 1999.
Some subscription apps offer a "Pause" or "Suspend" option alongside "Cancel". Pausing temporarily halts billing but may reactivate automatically after 30 or 90 days. If you want to end your subscription entirely, select "Cancel", not "Pause". Read the option labels carefully before confirming.
If you have followed the cancellation steps correctly but Booster continues to charge you, or if their support team refuses your cancellation request, you have legal recourse under Malaysian consumer law.
First, send a formal cancellation request via email to Booster's support address (listed in their Terms and Conditions) or through the help.booster.me contact form. Include your account details, your current subscription plan, your cancellation request date, and a clear statement that you do not authorize further charges. Request a written confirmation of cancellation within 5 business days. Keep a copy of this email for your records.
If Booster does not respond or refuses to cancel, contact your bank or credit card issuer and file a chargeback dispute. Most Malaysian banks will reverse unauthorized charges if you provide evidence of your cancellation attempt. Simultaneously, lodge a formal complaint with the Malaysian Consumer Tribunal (part of the Ministry of Domestic Trade and Consumer Affairs) or the direct MDTCA complaint line. Provide your cancellation confirmation screenshots, email correspondence, and bank statements showing the unauthorized charges. The Malaysian Consumer Tribunal can order Booster to refund you and may impose penalties on Booster for violations of the Consumer Protection Act 1999.
Yafee and its partner network have helped consumers recover erroneous charges from subscription services across Malaysia. The key is documentation: timestamps, email confirmations, screenshots, and bank records all strengthen your case.
Before you cancel, consider whether Booster is actually solving a problem on your phone or whether you are paying for unused features.
You might benefit from keeping Booster if your phone consistently runs low on storage, if battery life is a genuine concern, or if you have multiple devices and want automated maintenance across all of them. Booster's cleaning and optimization tools work best on older devices with limited RAM or heavily fragmented storage. If your phone is less than 2 years old and you regularly clear your cache, uninstall unused apps, and manage your storage manually, Booster may offer minimal benefit.
Cancel if you notice no difference in your phone's speed or battery life after using Booster for at least one month, if you find the app intrusive or unreliable, if the monthly cost outweighs the perceived value, or if you prefer manual optimization over automated tools. Many modern smartphones (especially flagship models running recent versions of iOS or Android) include built-in optimization features that reduce the need for third-party apps. If your phone is new or well-maintained, you may not need Booster at all.
| Reason to consider | Keep Booster | Cancel Booster |
|---|---|---|
| Phone age | 3+ years old, slowing down | Less than 2 years old, fast |
| Storage space | Frequently low (under 10% free) | Usually has 30%+ free space |
| Battery life | Drains rapidly, less than 2 hours per charge | Holds charge well (5+ hours of use) |
| App count | 100+ apps installed | Fewer than 50 apps |
| Cost vs. benefit | Clear improvement in performance after one month | No noticeable change or worsening after one month |
Use this checklist to ensure you cancel correctly and retain all necessary evidence.
If you need to contact Booster for any reason related to your subscription or cancellation, use the official channels published in their Terms and Conditions.
The primary support portal is the Booster Help Centre at help.booster.me, where you can access live chat (Monday to Friday, 9:00 AM to 5:00 PM MYT) and submit written support requests. Additional contact information is available in the General Terms and Conditions and Privacy Policy on booster.io and booster.club. Always keep a record of every support request you submit, including the date, time, and name of any support agent if provided, along with a summary of the issue and the resolution you requested.
If you are filing a formal complaint under the Consumer Protection Act 1999, address your complaint to the Malaysian Consumer Tribunal, which can be reached through the Ministry of Domestic Trade and Consumer Affairs website. Include your subscription details, evidence of your cancellation request, and documentation of any unauthorized charges.
Cancelling Booster in Malaysia is a straightforward process once you identify the correct platform and follow the prescribed steps. Your right to cancel is protected by the Consumer Protection Act 1999, and future billing must stop upon cancellation. If you cancel within 14 days of your initial subscription, you are entitled to a refund. After 14 days, you lose refund eligibility for the current period, but you retain the right to cancel future charges.
The critical actions are: confirm your subscription platform, cancel on that platform (not another), screenshot your confirmation, and monitor your bank statement for erroneous charges. If Booster refuses to cancel or continues to charge you, escalate to your bank and the Malaysian Consumer Tribunal.
