Terms of service

Last updated 12 September 2026

The service

Rostack is an operations platform for Roblox groups: ranking, staff management, activity tracking and Robux payouts, with an audit trail. It works by calling Roblox's APIs on your behalf with credentials you choose to connect. Rostack is operated by an individual developer, not a company, and is not affiliated with or endorsed by Roblox Corporation. Creating an account means agreeing to these terms.

Your account

You must be at least 16 to use Rostack, and an adult, or have a parent's or guardian's permission, to buy a paid plan. You are responsible for what is done with your account and for keeping your sign-in, and any authenticator you enrol, to yourself. If you own a workspace, you are responsible for who you give seats to and what you let them do; Rostack caps every seat at that person's Roblox rank, but the grant within that cap is yours.

Plans

Every workspace is on a plan. Free is for trying Rostack with a small team: it tracks a limited number of staff, shows a shorter history, has smaller allowances, and leaves out payouts and some parts of the product. Plus and Max are paid plans with the whole product, and Max has larger quotas. Custom plans are agreed in writing. What each plan includes, and its limits, are on the pricing page and in the workspace's settings, and those are the ones that apply.

A plan belongs to one workspace, and only that workspace's owner can choose, change or cancel it. Paid plans never count staff.

Payment and renewal

Paid plans are priced per workspace, charged monthly in advance in US dollars, and paid through Stripe, which processes the payment; Rostack never sees your card. A plan renews automatically each month, on the day it started, until it is cancelled. Any tax that applies is shown at checkout before you pay. Receipts and invoices are in the billing portal, under Manage billing in the workspace's settings.

Changing plan, cancelling, and moving down

You can move between Plus and Max at any time, and Stripe adjusts the charge for the rest of the month. You can cancel at any time from Manage billing: the plan stays on until the end of the month already paid for, and the workspace moves to Free after that.

Moving to a smaller plan never deletes anything. What the new plan does not include is kept and waits: payout schedules pause at their next run, parts of the product the plan leaves out lock with their data intact, Discord notices and your own branding stop, staff already tracked stay while nobody new is added past the plan's limit, and history older than the plan shows stays stored and comes back on a plan that shows it.

Refunds, and the right to withdraw

If you are a consumer in the European Union or the United Kingdom, you can withdraw from a paid plan within 14 days of first subscribing to it, without giving a reason, and get a full refund. Write to support@rostack.app with the workspace's name, or send the form below. The refund goes back to the card you paid with, within 14 days of your message, and the workspace moves to Free.

Outside that, payments are not refunded for part of a month, except where the law requires it. A charge you do not recognise, or one taken after you cancelled, is always looked into: write to support@rostack.app.

If a payment fails

Stripe tries again over the following days, the plan stays on meanwhile, and the dashboard says so. If the payment still cannot be collected, the workspace moves to Free, with the same care as any move to a smaller plan: nothing is deleted.

Price changes and Custom plans

Rostack gives at least 30 days' notice of a price change, in the product and by writing to the email address given at checkout. A new price applies from the first renewal after the notice, and you can cancel before then. A Custom plan follows its own written agreement, which takes precedence over these terms where the two differ.

Robux payouts

Rostack plans, approves and sends Robux payouts according to the instructions and limits you set. Robux, once Roblox has processed a payout, cannot be reversed by Rostack or by you. Rostack's guardrails, the approval step and the per-action authenticator code exist to reduce mistakes; they cannot eliminate them, and the amounts you approve are your responsibility. Payouts are between your community and the people it pays: Rostack is not a party to them, holds no Robux and no funds, and Roblox's own terms govern Robux. What you pay for a Rostack plan and the Robux a community pays out never meet.

Your community's data

What a workspace records about its members, such as staff records, in-game activity, sessions, conduct notes, bans and applications, belongs to that community. Rostack stores and processes it only to provide the service, on the workspace's instructions, and never sells it or uses it for anything else. As the workspace owner you decide what is recorded, and you are responsible for having a lawful reason to record it and for telling your members. The privacy policy explains what Rostack does with it, and you can point your members there.

What you agree not to do

Use Rostack in a way that breaks Roblox's Terms of Use or Community Standards; connect a credential for a Roblox account or group you do not own or administer; use the ranking API to harass, extort or defraud; attempt to access another workspace's data; get around a plan's limits, or resell access to Rostack; or probe, scan or attack the service. Rostack may suspend an account that does any of these, and will say why.

Credentials you connect

Ranking uses a Roblox Open Cloud API key you create. Payouts require a Roblox account cookie, because Roblox publishes no payout API; that cookie acts as the whole Roblox account. Rostack encrypts it so the website itself cannot read it, and the security page describes exactly how. Connecting it is your decision, and Rostack recommends an account that owns nothing you would mind losing.

Ending

You can cancel a plan or delete your account at any time. Rostack may suspend or close an account or workspace that breaks these terms, and will say why. If Rostack ends a paid plan for any other reason, including stopping the service, it refunds the part of the month not used. What is kept after an account is deleted is listed in the privacy policy.

Availability and liability

Rostack depends on Roblox's APIs, which Roblox may change, rate-limit or withdraw without notice, so it cannot promise to be available at every moment or free of every error.

If you are a consumer, you have the legal guarantee that a digital service matches its description and works as it should for as long as you use it, and nothing in these terms limits that guarantee or any other right the law gives you. If you use Rostack for a business, then to the extent the law allows, Rostack is not liable for indirect or consequential loss, and its total liability for any claim is limited to what you paid Rostack in the twelve months before the claim.

Changes to these terms

Rostack may change these terms. Material changes are announced in the product at least 30 days before they take effect, and the date at the top changes when the terms do. If you do not accept a change, you can cancel before it applies; using Rostack after that date means accepting it.

Law and disputes

These terms are governed by French law. If you are a consumer, you also keep the protection of the mandatory rules of the country where you live, and can go to its courts. Before anything formal, please write to legal@rostack.app: almost everything is settled faster that way.
