Terms of Service

01Agreement to these terms

These Terms of Service are a binding contract between you and , a limited liability company formed in and doing business as SpoolBase (“SpoolBase”, “we”, “us”). They govern your use of the SpoolBase website, web application, mobile applications, and any related services (together, the Service).

By creating an account, or by using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy, Cookies & Tracking notice, and Refund Policy are part of this agreement.

02Who can use SpoolBase

To use the Service you must:

• Be at least 16 years old. To buy a paid plan you must be at least 18, or the age of majority where you live, whichever is higher.
• Have the legal capacity to enter into this agreement. If you are agreeing on behalf of a company or other organisation, you confirm you are authorised to bind it, and “you” then means that organisation.
• Not be barred from using the Service under the laws of your country or of the United States, and not be located in a country subject to a US government embargo or designated as supporting terrorism.
• Not have had a SpoolBase account previously terminated by us for breach of these Terms, unless we have given you written permission.

03Your account

You need an account to use the Service. You agree to give accurate information when you register and to keep it current.

You are responsible for your account and for everything that happens under it. Keep your password confidential, use one you do not use anywhere else, and tell us at as soon as you suspect unauthorised access. We are not liable for losses arising from someone else using your credentials, unless the cause was our own failure.

One account is for one person. Do not share your login. If you need multiple people to use SpoolBase, see section 07.

You may delete your account at any time from Settings. What happens to your data when you do is set out in the Privacy Policy.

04What SpoolBase is — and what it isn't

SpoolBase keeps a running record of your 3D printing filament. It connects to your Bambu Lab account, watches what your printers report, and deducts filament from the spool it believes was used, asking you when it is not sure.

It is an estimate, not a measurement

It does not control your printer

SpoolBase reads. It does not start, pause, stop, or modify prints, and it does not change any setting on your printer or in your Bambu Lab account. Nothing in the Service is a safety system, and it must not be treated as one.

It depends on Bambu Lab

The Service works by consuming data from Bambu Lab's cloud systems. We have no control over those systems and no agreement with Bambu Lab. If Bambu Lab changes its interfaces, restricts access, or has an outage, SpoolBase may stop working correctly, partially or entirely, with or without warning. We will do our best to adapt, but we cannot promise continued compatibility, and this risk is one you accept by using the Service.

05Connecting your Bambu Lab account

To connect a printer, you give SpoolBase your Bambu Lab credentials. By doing so:

• You authorise us to access your Bambu Lab account on your behalf, for the sole purpose of reading printer status, AMS contents, and print history in order to provide the Service.
• You confirm that the account is yours, or that you are authorised by its owner to connect it, and that doing so does not breach your agreement with Bambu Lab.
• You acknowledge that your relationship with Bambu Lab is governed by their terms, that we are not a party to it, and that we are not responsible for anything Bambu Lab does — including suspending, restricting, or terminating your account with them.

How we handle those credentials is set out in detail in the Privacy Policy: your password is passed through to Bambu Lab and discarded, never stored, and the resulting tokens are encrypted at rest. You can disconnect at any time from Settings.

SpoolBase is an independent product. It is not affiliated with, endorsed by, sponsored by, or otherwise connected to Bambu Lab. “Bambu Lab”, “Bambu Studio”, “AMS” and related marks belong to their owners and are used here only to describe compatibility.

06Plans, pricing and billing

Free plan

The Free plan is free, with no time limit and no card required. It includes the full automation of the Service, limited to 20 active spools and 2 printers. Every feature that tracks your filament automatically is included, so you can judge whether SpoolBase works for you before paying us anything. Some planning and reporting tools may be available only on a paid plan.

The 20-spool limit governs what the Service displays, not only what you can add. If your account holds more than 20 active spools while on the Free plan — which normally happens when a paid subscription ends — the Service shows the 20 earliest active spools in your inventory and hides the rest. Hidden spools are retained, not deleted or altered, and they reappear in full as soon as you subscribe again. Spools marked empty do not count toward the limit.

Your print history is not subject to the limit. Your complete record of print jobs and filament deductions stays visible on the Free plan, including jobs that used spools currently hidden.

Paid plans

Paid plans are billed annually, in advance, at the price shown when you subscribe. Unless stated otherwise, prices are in US dollars and exclude any applicable sales tax, VAT, or GST, which we will add where we are required to collect it.

Automatic renewal

Subscriptions renew automatically at the end of each billing period, at the then-current price, until you cancel. You can cancel at any time from Settings, and you keep paid access until the end of the period you have already paid for. Cancelling stops future charges; it is not a refund request. See the Refund Policy.

Price changes

We may change prices. If we increase the price of a plan you are on, we will give you at least 30 days' notice by email before it applies to you, and the new price will take effect at your next renewal. If you do not want to pay it, cancel before then. We will never change the price of a period you have already paid for.

Failed payments

If a payment fails, we will retry and let you know. If it remains unpaid, we may downgrade your account to the Free plan. We will not delete your data because a payment failed — but the Free plan's limits, including the visibility rule above, will apply until the account is paid up again.

Payments and app stores

Card payments are processed by Stripe under Stripe's own terms; we never receive your card number. If you subscribe through the Apple App Store or Google Play, that purchase is made with Apple or Google, their terms govern it, billing and cancellation happen in your account with them, and any refund must be requested from them, not from us.

Taxes

You are responsible for any taxes on your purchase other than taxes on our income.

07Team and business accounts

Where we offer a plan intended for print farms, businesses, or shared use, these additional terms apply.

• The person or organisation that sets up the account is the account owner, is responsible for billing, and controls who has access.
• The account owner is responsible for the conduct of everyone it grants access to, and for ensuring each of them complies with these Terms.
• The account owner may add, remove, and change the permissions of users, and may access data those users create within the account. If you are added to someone else's SpoolBase account, understand that the owner can see what you record in it.
• Seats may not be shared between people. Each person needs their own login.
• If you use SpoolBase for business purposes, you do so as a business and not a consumer, and any consumer-specific protections referred to in these Terms may not apply to you.
• If you need a data processing agreement to use SpoolBase in your business, contact us at .

08Acceptable use

Use SpoolBase for tracking your filament. Do not do any of the following:

• Access another user's account or data, or attempt to.
• Probe, scan, or test the security of the Service, except as permitted under our security disclosure policy.
• Interfere with or disrupt the Service, or place an unreasonable load on it — including scraping, automated bulk requests, or running the Service through infrastructure designed to multiply your usage.
• Reverse engineer, decompile, or attempt to derive the source code of the Service, except to the extent that restriction is unenforceable where you live.
• Resell, sublicense, rent, or provide the Service to third parties as your own product, or use it to build a competing service.
• Use the Service to store or transmit anything unlawful, infringing, malicious, or harmful, or to violate anyone's rights.
• Connect a Bambu Lab account you are not authorised to use.
• Misrepresent your identity or affiliation, or use the Service in a way that suggests an endorsement by us or by Bambu Lab that does not exist.
• Circumvent plan limits, including by creating multiple accounts to exceed the Free plan's spool limit.
• Remove or obscure any proprietary notice in the Service.

We may investigate suspected breaches and take proportionate action, up to suspension or termination under section 15.

09Your data

Your data is yours. Your inventory, your print history, your notes and your purchase records belong to you. We do not claim ownership of any of it.

You grant us a limited, non-exclusive, worldwide, royalty-free licence to host, store, copy, transmit, process, and display your data solely to operate and improve the Service for you, and to make backups. This licence exists so we can legally run the servers your data sits on. It ends when your data is deleted.

You are responsible for the accuracy and legality of what you put into SpoolBase, and for having the right to put it there.

Aggregated and product data

We may use aggregated, de-identified information — statistics that cannot reasonably be linked back to you or your account — to understand and improve the Service. Separately, as described in the Privacy Policy, filament products your printer reports may be added to a shared catalogue of materials and colours. That catalogue describes filament, not people, and carries no link to your identity.

Exporting and backups

You can view and copy your data through the Service, and you can request an export as described in the Privacy Policy. Although we back up our databases nightly, you should keep your own record of anything you cannot afford to lose. We are not a backup service.

10Our intellectual property

The Service — its software, design, interface, text, graphics, logos, and the SpoolBase name — belongs to us or our licensors and is protected by copyright, trademark, and other laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the Service in accordance with these Terms. Nothing else is granted, by implication or otherwise.

Third-party names and marks referred to in the Service, including Bambu Lab's, belong to their respective owners.

11Feedback

If you send us an idea, suggestion, or bug report, thank you — genuinely, it is how the product gets better. You agree we may use it freely, without obligation, attribution, or payment, and without it being treated as confidential. You are not giving up any patent or copyright you already hold; you are just letting us act on the suggestion.

12Third-party services

The Service depends on third parties, including Bambu Lab, our hosting provider, our payment processor, and Apple's and Google's push notification services. Your use of those services is governed by their terms, not ours. We are not responsible for their acts, omissions, outages, pricing, or changes, and their failure does not make us liable to you — though it may make the Service unavailable, and we will tell you what we know when it does.

13Availability, changes and maturity of the Service

We may modify, suspend, or discontinue any part of the Service at any time. If we discontinue the Service as a whole, or remove a feature you are paying for, we will give you at least 30 days' notice and a pro-rata refund of any prepaid, unused subscription time, and we will give you a reasonable opportunity to export your data before it goes.

Features marked as beta, preview, or experimental are provided as-is, may change or disappear without notice, and are excluded from any commitment in these Terms.

14Suspension and termination

By you

You may stop using the Service at any time and delete your account from Settings. If you are on a paid plan, cancelling stops the next charge; see the Refund Policy for what, if anything, is refunded.

By us

We may suspend or terminate your account if you materially breach these Terms, if your use puts the Service or other users at risk, if we are required to by law, or if your payment remains unpaid after we have told you about it.

Except where an immediate suspension is necessary — to stop ongoing harm, respond to a security incident, or comply with a legal obligation — we will give you notice and, where the breach can be fixed, a reasonable opportunity to fix it before we terminate.

If we terminate your account for a reason other than your breach, we will refund any prepaid, unused subscription time.

What happens afterwards

On termination, your right to use the Service ends. We will keep your data for 30 days so you can ask for it back or export it, after which it is permanently erased as described in the Privacy Policy. The sections that by their nature should survive — 09 (your data), 10, 11, 15–19 and 21 — survive termination.

15Disclaimers

Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you. Nothing here limits any non-excludable statutory right you have as a consumer — including, in the EU, UK, and Australia, rights that cannot be contracted away.

16Limitation of liability

These limits do not apply to liability that cannot lawfully be limited — including, in most places, our own fraud, wilful misconduct, gross negligence, or death or personal injury caused by our negligence. If you are a consumer in the EU or UK, these limits apply only to the extent permitted by the consumer law that protects you.

This allocation of risk is a fundamental part of the bargain between us, and it is reflected in what we charge for the Service.

17Indemnification

You agree to indemnify and hold us harmless from any claim, demand, loss, or expense (including reasonable legal fees) arising from your use of the Service, your breach of these Terms, your violation of any law or third-party right, or the data you put into the Service. We will notify you of any such claim, let you control the defence with counsel we reasonably approve, and cooperate with you — and you will not settle anything that imposes an obligation on us without our consent.

If you are a consumer, this section applies only to the extent permitted by the law that protects you.

18Resolving disputes

Talk to us first

Before starting any formal proceeding, you agree to contact us at describing the problem and what you want, and to give us 30 days to resolve it. We agree to do the same for you. Most disagreements end here, and we would rather they did.

Arbitration

If we cannot resolve it informally, any dispute arising out of or relating to these Terms or the Service will be settled by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, before a single arbitrator. Arbitration will take place in the county where you live, or remotely by phone or video at your choice. The arbitrator's decision is final and may be entered as a judgment in any court with jurisdiction.

Where the AAA rules require us to pay the filing and arbitrator fees for a consumer claim, we will. Where they do not, and paying them would be a genuine barrier to you bringing your claim, we will pay them anyway on request.

What arbitration does not cover

• Either of us may bring a claim in small claims court if it qualifies.
• Either of us may seek an injunction in court to protect intellectual property or stop unauthorised access to the Service.

No class actions

Disputes will be brought only in your or our individual capacity, and not as a plaintiff or class member in any class, consolidated, or representative proceeding. The arbitrator may not consolidate claims or preside over any form of representative proceeding. If this paragraph is found unenforceable, the whole of this section 18 is void and disputes go to the courts identified in section 19.

How to opt out

You can reject this arbitration agreement. Email with “Arbitration Opt-Out” in the subject and your account email in the body, within 30 days of first accepting these Terms. That is all it takes — no reason required, and it will not affect your account, your plan, or how we treat you in any way. If you opt out, disputes go to the courts identified in section 19, and the rest of these Terms continue to apply.

If you are a consumer outside the United States

If you are a consumer resident in the EU, UK, or another jurisdiction whose law gives you the right to bring proceedings in your local courts and to have your local law apply, this section does not take that away from you. It applies only to the extent your law permits.

19Governing law and venue

These Terms are governed by the laws of the State of and the United States, without regard to conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Where a dispute is not subject to arbitration under section 18, or where section 18 does not apply to you, it will be brought exclusively in the state or federal courts located in , and we each consent to their jurisdiction.

If you are a consumer in the EU or UK, you keep the benefit of the mandatory consumer protections of your country of residence, and may bring proceedings in your local courts. EU consumers may also use the European Commission's online dispute resolution platform.

20Changes to these terms

We may update these Terms. When we do, we will change the “Last updated” date and keep the current version at this address.

For a material change — one that meaningfully reduces your rights or increases your obligations — we will give you at least 30 days' notice before it takes effect, by email to your account address and by a notice in the app. Continuing to use the Service after a change takes effect means you accept it. If you do not accept it, stop using the Service and delete your account before then; if you are on a paid plan, we will refund the unused portion of your current period.

Minor changes — corrections, clarifications, new features that do not affect your rights — take effect when posted.

21General terms

• Entire agreement. These Terms, with the Privacy Policy, Cookies notice, and Refund Policy, are the whole agreement between us about the Service, and replace anything said before.
• Severability. If any provision is held unenforceable, it is modified to the minimum extent necessary or severed, and the rest stays in force.
• No waiver. If we do not enforce a provision, that is not a waiver of our right to enforce it later.
• Assignment. You may not assign these Terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets, on notice to you.
• Force majeure. Neither of us is liable for failure to perform caused by events beyond reasonable control, including natural disasters, war, civil unrest, labour disputes, government action, internet or utility failures, and the acts or failures of upstream providers.
• Notices. We will send notices to the email address on your account, or post them in the Service; they are effective when sent or posted. Send notices to us at . It is your responsibility to keep your email address current.
• Relationship. Nothing here creates a partnership, joint venture, agency, or employment relationship.
• No third-party beneficiaries. These Terms benefit only you and us, except that Apple and Google are third-party beneficiaries of the app-store provisions in section 06, entitled to enforce them.
• Export and sanctions. You agree to comply with US export control and sanctions laws in using the Service.
• Language. These Terms are written in English. Any translation is for convenience, and the English version controls.
