Terms of Service

Last updated: 25 August 2026

These Terms are a binding agreement between you and Mystic Systems LLC(“Blueberry”, “we”, “us”) covering the Blueberry Client software, this website, and everything you buy through them (the “Service”).

By installing, signing in, or purchasing, you accept these Terms. If you do not accept them, do not use the Service.

Section 13 contains a binding arbitration clause and a class-action waiver that affect how disputes are resolved.

1. Eligibility

You must be at least 13 years old. If you are under the age of majority where you live, you may use the Service only with a parent or guardian’s consent, and they accept these Terms on your behalf.

You must already own a legitimate, lawfully purchased copy of Minecraft: Bedrock Edition, licensed to the Microsoft/Xbox account you sign in with. Blueberry is an add-on for a game you already own.

1a. We do not supply Minecraft

Blueberry does not include, bundle, distribute, resell, crack, emulate, or otherwise provide Minecraft or any part of it. We do not host, link to, or assist with pirated, cracked, or unlicensed copies, and we provide no means of circumventing Minecraft’s licensing, DRM, or account requirements.

Blueberry contains none of Mojang’s or Microsoft’s code or assets. You must install Minecraft yourself through official channels and sign in with the Microsoft account that owns it — the client will not run otherwise. Using Blueberry with an unlicensed copy is a breach of these Terms and grounds for immediate termination without refund.

2. Not affiliated with Mojang or Microsoft

Blueberry is an independent third-party product. It is NOT approved by, associated with, or endorsed by Mojang Studios, Microsoft, or Minecraft. “Minecraft” is a trademark of Mojang Synergies AB. We claim no rights in it. Your use of Minecraft remains governed by Microsoft’s and Mojang’s terms; where they conflict with your use of Blueberry, theirs control.

3. Licence to use the software

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use Blueberry on devices you control, for personal, non-commercial use.

You may not sell, rent, sublicense, or redistribute the Service; reverse engineer, decompile, or disassemble it except where that right cannot lawfully be excluded; circumvent its licensing, authentication, or entitlement checks; use it to build a competing product; or use it unlawfully. We retain all rights not expressly granted. You are licensed to use the software. You do not own it.

4. Accounts

You are responsible for your account and everything done through it. One account is for one person; sharing, selling, or transferring accounts is prohibited. Only one device may be signed in at a time. You must not use the Service if previously banned, or create a new account to evade a ban.

5. Virtual items and Blueberries — what you are actually buying

“Blueberries” (our in-app currency) and cosmetics such as cloaks are licences, not property. When you acquire them:

• You receive a limited, personal, non-transferable, revocable licence to use that item within Blueberry. Nothing more.
• You do not own them. They are not your property, not a financial asset, and not a security, commodity, or currency of any kind.
• They have no monetary value and cannot be redeemed for money.
• They cannot be sold, traded, gifted, transferred, or exchanged. Any attempt to do so outside the Service is void and may result in termination.
• We may modify, suspend, replace, re-price, or remove any item, and change the price or availability of Blueberries, at any time.
• Your licence ends when your access ends — and you are owed nothing for unused Blueberries or cosmetics at that point, except as set out in section 11.

Blueberries are not a stored-value or prepaid instrument and are not transferable outside the Service.

6. Payments and refunds

Prices are shown at checkout and may change. Payments are handled by Stripe under its Managed Payments service, which means Link (Stripe) is the merchant of record for your purchase and sells the item to you. Stripe’s terms apply to the transaction, and Stripe calculates, collects, and remits any sales tax, VAT, or GST. We remain responsible for the Service itself and for product support.

On your statement this purchase appears as LINK.COM* BLUEBERRY — not as “Blueberry Client” or “Mystic Systems”. Please check this before reporting a charge as unrecognised.

All sales are final and non-refundable except where a refund is required by law. Digital items are delivered immediately, and by completing a purchase you request immediate delivery. Because Stripe is the merchant of record, Stripe may also issue a refund on its own initiative; where it does, Section 6a still applies and the items that payment bought are revoked.

Consumers in the UK and EU: you normally have a 14-day right to cancel digital content. By purchasing and requesting immediate access — which you confirm at checkout — you expressly consent to immediate performance and acknowledge that you lose that right to cancel once delivery begins.

We may refund at our discretion.

6a. Chargebacks, reversals, and payment fraud

Charging back a payment for items you have received is a breach of these Terms. If you dispute or reverse a payment, or a payment is reversed for any reason:

• The items that payment bought are revoked automatically — Blueberries debited back, cosmetics removed, licences ended — whether or not you have already used them.
• Reversing a payment for Blueberries you have already spent will leave your balance negative. That is intended. You cannot spend again until it is settled.
• We may suspend or terminate the account immediately, and refuse future purchases from you or any account, payment method, or device we reasonably associate with you.
• We may charge you the fees our payment processor charges us for the dispute, and recover reasonable collection costs where the law permits.

You agree to contact us first and give us a reasonable opportunity to resolve any billing problem before disputing with your bank. We keep a permanent record of every currency movement, purchase, and grant. Disputes are answered by Stripe as merchant of record, and the outcome of a dispute does not limit our rights under this Section.

If you did not authorise a payment — a child used your card, or your card was stolen — email support@blueberryclient.com. We will refund a genuinely unauthorised charge and revoke what it bought.

6b. Fraud, exploits, and abuse

You must not obtain Blueberries, cosmetics, or access by any means other than paying for them or receiving them from us. That includes exploiting a bug, duplication glitch, or pricing error; using stolen or unauthorised payment methods; creating accounts to abuse introductory offers; or reselling or transferring items or accounts.

Anything obtained this way is void. We may remove it, reverse the balance, and terminate the accounts involved, without refund and without notice.

7. Acceptable use

You must not use the Service to break the law; harass, abuse, threaten, or harm anyone; transmit unlawful, hateful, or sexually exploitative content; disrupt or attack our infrastructure; automate, scrape, or place unreasonable load on our systems; or exploit bugs or pricing errors.

Proximity chat carries your live voice to other players. Do not use it to harass or abuse others. We cannot hear your voice — it is end-to-end encrypted — so moderation relies on reports, and we will disable voice for accounts we receive credible reports about.

7a. Anti-tamper and device-level enforcement

Blueberry checks the device it is running on. Each time the launcher starts it reports a hardware fingerprint — your Windows MachineGuid, your computer name, and the MAC address of every physical network adapter — and we record the IP address you connected from. Section 2.7 of the Privacy Policy sets out exactly what is stored and for how long.

The launcher also detects debuggers and reverse-engineering tools. If it finds one running it records that fact and closes itself. This is how the restrictions in Section 3 are enforced in practice.

Enforcement is not limited to your account. Where we ban for cause we may apply it to the device fingerprint and the IP address as well, so that a new account on the same machine or network does not simply restore access. A consequence worth understanding: if you share a computer or a home network with someone who is banned, you may be affected too. Contact support if that happens and we will look at it.

Attempting to defeat any of this — spoofing hardware identifiers, masking your connection to evade a ban, or interfering with these checks — is a breach of these Terms and is treated as ban evasion under Section 4.

8. Third-party servers and bans

Blueberry does not guarantee that any third-party Minecraft server will permit its use. Server operators and anti-cheat systems set their own rules. Using Blueberry, or any particular feature of it, may get you kicked or banned on servers we do not control. That risk is entirely yours. We are not responsible for any ban, loss of progress, loss of items, or loss of access to any third-party service, and a ban is not grounds for a refund.

9. Software that modifies Minecraft

Blueberry loads into a running copy of Minecraft on your PC and may change files in your Minecraft installation folder to function. You authorise this. Software of this kind can be affected by Minecraft updates, can stop working without notice, and can in rare cases cause the game to crash. You use it at your own risk and are responsible for backing up anything you care about.

10. Availability

We may change, suspend, or discontinue any part of the Service at any time. We do not promise any level of uptime. Access depends on Minecraft, Microsoft, and other services we do not control.

11. Termination

Termination for cause — no refund. We may suspend or terminate your access immediately and without notice where you breach these Terms, where we reasonably suspect fraud, chargeback abuse, stolen payment methods, exploit abuse, or ban evasion, or where we are legally required to. Your licences end immediately, including Blueberries and cosmetics, and no refund is owed.

Termination without cause. If we end your access for our own reasons — including discontinuing the Service — and you have not breached these Terms, we will refund the unused portion of anything you have paid for, unless the law requires more.

You may stop using the Service and request deletion at any time; that is voluntary and no refund is owed. Sections 5, 6, 6a, 6b, 7a, 8, 9, 12, 13 and 14 survive termination.

12. Disclaimers and limitation of liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation.

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, nor for lost profits, lost data, lost progress, or loss of access to any third-party service — including bans.

Our total aggregate liability for any and all claims is capped at the greater of (a) the total amount you paid us in the 6 months before the claim, or (b) USD $50. This is a maximum, not a payment.

Nothing here excludes liability that cannot lawfully be excluded — including for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or your non-excludable statutory consumer rights. If you are a consumer, you keep any rights your local law gives you that cannot be waived.

13. Disputes, arbitration, and class waiver

These Terms are governed by the laws of the State of Wyoming, USA, without regard to conflict-of-law rules.

Informal resolution first. Before starting any formal proceeding, contact us and give us 60 days to resolve it.

Arbitration. If we cannot resolve it, any dispute will be settled by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court. Either party may still bring a qualifying claim in small-claims court.

Class-action waiver. You and we each waive any right to bring or participate in a class, collective, consolidated, or representative action.

Opt out. You may reject this arbitration agreement by emailing support@blueberryclient.com within 30 days of first accepting these Terms, stating your name and that you opt out. Opting out costs you nothing and does not affect your access or anything else in these Terms.

Consumers in the UK/EU: this section applies only so far as your local law allows. You keep the right to bring proceedings in your country of residence and to rely on its mandatory consumer protections.

14. General

Changes. We may update these Terms. Material changes will be announced in the launcher or on the website before they take effect, and continued use after that means you accept them.

If you do not accept a change, stop using the Service and tell us at support@blueberryclient.com. You may keep using anything you had already paid for under the previous Terms until it is used up, or ask us to refund its unused portion. We will not cut off something you have paid for merely because you declined a later revision. This does not apply where the change is required by law, or where your account is terminated for cause under section 11.

Entire agreement. These Terms and the Privacy Policy are the whole agreement between us. Severability. If any provision is unenforceable, the rest stays in force. No waiver. Not enforcing a right is not a waiver of it. Assignment. You may not assign these Terms; we may, including in a sale of the business.
