Developer Terms

Last updated 13 November 2026. These changes apply from 13 December 2026, and to apps made from 13 November 2026 straight away; until then, the previous version applies to apps made before. These terms add to Grumble's Terms of Service and Community Rules, which apply to your app too.

What's changing on 13 December 2026

A limit on what we can be liable for, with your rights under the Australian Consumer Law untouched, and at least 30 days' notice of changes to these terms and of API changes that break things.

1. Who these are for

You agree to these terms when you create an application in the Developer Portal, or use Grumble's API, gateway, webhooks or bots in any other way. "Your app" means your application, its bot, and the code and services behind them. If you build for an organisation, you agree for it too.

2. What you may do

You may use Grumble's API to build bots and apps that people choose to add to their servers or use. The API is free. Using it doesn't give you any rights in Grumble's name, pug or other branding. Don't use them in a way that suggests we made or endorse your app.

3. People's privacy

Grumble is built so that people don't have to give up their privacy, and your app has to keep it that way.

• Only take what your app needs to do what people added it for, and keep it only as long as that takes.
• Never sell or share what your app gets from Grumble, or use it for advertising, tracking or profiling people.
• Never try to work out who someone is (their real name, where they are, other accounts they have) or link their Grumble account to anything outside Grumble.
• Don't train AI models on what people post, unless everyone whose content it is has clearly agreed.
• Say what you do. If your app keeps anything about people, publish a privacy policy that explains what, why and for how long. Delete someone's data when they ask, or when your bot leaves a server.
• Don't get around privacy protections, including encrypted DMs, age-restricted channels, blocks, and the rules about who can contact whom.

4. Safety

• Your app must follow the Community Rules, and must not be used to share anything they forbid.
• Never use your app to send sexual content to anyone under 18, or to contact anyone under 16 one to one unless they've said a parent or carer agrees.
• If your app lets people post or share things, give server moderators a way to remove them, and act on what's reported to you.
• If you find child sexual abuse material, a threat to someone's life, or a security problem, tell us straight away through the Safety Centre.

5. Using the API properly

• Bots only. Automate bot accounts, not people's accounts. "Self-bots" aren't allowed.
• Respect rate limits and don't try to get around them, for example with many bots or accounts.
• No scraping. Don't collect messages, members or profiles in bulk, or copy servers you weren't added to for that.
• No spam. Don't mass-message people, join servers through invites people didn't give your bot, or send things people didn't ask for.
• Keep tokens secret. You're responsible for anything done with your app's token. If it leaks, reset it.
• Don't attack Grumble. That means no probing for weaknesses without our permission, no overloading the service and no interfering with other apps.
• Ask only for the permissions and intents your app uses.

6. Our part

• We may change the API. We give at least 30 days' notice of changes that break things, unless the law or security needs a change sooner.
• We may limit, suspend or remove an app, or reset its token, if it breaks these terms, puts people at risk, or harms Grumble. Where we can, we'll tell you why.
• The API is provided as it is. Nothing here takes away rights you have under the Australian Consumer Law or other laws that can't be excluded, or limits our liability for death or personal injury caused by our negligence, for fraud or gross negligence. Apart from that, and as far as the law allows, we aren't liable for indirect or consequential loss, and our total liability to you for anything to do with the API is limited to A$100.

7. Leaving

You can delete your app at any time in the Developer Portal. Its bot leaves every server and its token stops working. If these terms end, you must stop using the API and delete what your app got from Grumble, except anything the law requires you to keep.

8. Changes and law

We may update these terms. When a change matters, we'll say so in the Developer Portal at least 30 days before it applies, unless the law or security needs it sooner. These terms are governed by the law in force in Victoria, Australia. Grumble is run by Aternix (ABN 85 475 523 046). Reach us through our contact page or at admin@aternix.com.
