Terms of Service

Last updated 2026-05-26.

1. What Twico is

Twico is a desktop application that helps you handle inbound messages on Slack. It reads your unread DMs and threads, drafts replies in your voice using an LLM, and posts those replies from your Slack account — not from a bot.

2. How Twico authenticates with Slack — and the risk you accept

Twico authenticates with Slack using the same credentials your real Slack desktop client uses— the workspace’s xoxc-prefixed session token plus the d cookie. We extract those credentials from the Slack desktop client installed on your machine. We do this locally, on your computer; the credentials never leave your machine.

Slack’s terms of service restrict automation of user accounts and generally require third-party access via official bot or app APIs that post as a bot, not as you. By using Twico:

• You acknowledge that your use of Twico may violate Slack’s terms of service.
• You accept that Slack may suspend, restrict, or terminate your accountas a result, and that we offer no warranty or remedy against that outcome.
• You represent that you have the right to access the workspaces you connect to Twico (e.g. you are not connecting a workspace you were forbidden from automating by an employer or admin).
• We have no relationship with Slack. We are not endorsed by, affiliated with, or licensed by Slack Technologies, LLC.

3. Risk profile

Slack is a medium-risk platform for this kind of automation: workspace admins can audit message activity, and Enterprise Grid organizations in particular have higher detection capability. Connect only personal or workspaces where you have permission to automate.

4. Acceptable use

You agree not to use Twico to:

• Access accounts you do not have permission to operate.
• Send mass messages, spam, or unsolicited communications.
• Impersonate someone other than yourself.
• Violate any applicable law in your jurisdiction or the recipient’s.

5. What Twico does with your data

Twico runs locally on your machine. Your messages, voice profile, and knowledge hub are stored in a local SQLite database. We don’t see them.

When you use the LLM features, your messages are sent to the language-model provider you choose (OpenRouter by default; Ollama if you pick local mode). On the paid plan, we proxy OpenRouter requests through our servers solely to bill your usage; we do not store the message contents. Their privacy is governed by the LLM provider’s privacy policy.

We collect crash reports via Sentry (opt-in) and product-usage events via PostHog (opt-in). Neither includes message contents.

6. Subscriptions and refunds

Twico is offered on a monthly or annual subscription. You may cancel at any time from the billing page; cancellation takes effect at the end of your current billing period. We do not offer prorated refunds for unused subscription time except where required by your local law.

7. Disclaimer of warranties

Twico is provided “as is”, without warranty of any kind, express or implied. We do not warrant that Twico will be uninterrupted, error-free, or that third-party platforms will continue to function with the authentication methods Twico relies on. Platform changes may break Twico at any time.

8. Limitation of liability

To the maximum extent permitted by law, Kupia Lab’s total liability to you for any claim arising out of your use of Twico is capped at the amount you paid us in the twelve months preceding the claim. In particular, we are not liable for account suspensions, lost work, or any consequential damages resulting from third-party platform enforcement against your account.

9. Indemnification

You agree to indemnify and hold harmless Kupia Laband its officers from any claims, damages, or expenses (including reasonable attorneys’ fees) arising from your use of Twico in violation of these terms or any third-party platform’s terms of service.

10. Governing law

These terms are governed by the laws of California, USA, without regard to its conflict-of-laws principles. Disputes shall be resolved in the courts of San Francisco County, California.

11. Changes to these terms

We may update these terms from time to time. Material changes will be announced via email to your account’s contact address and via in-app notice. Continued use after the effective date constitutes acceptance.
