Terms and Conditions for PostOnce

Effective Date: September 29, 2026

Welcome to PostOnce. These Terms of Service ("Terms") govern your access to and use of PostOnce, available at https://postonce.to, including our website, dashboard, publishing tools, automation workflows, APIs, MCP server, integrations with AI assistants such as ChatGPT, and related services (collectively, the "Service"). By creating an account, connecting a social account, subscribing, authorizing an integration, or otherwise using the Service, you agree to these Terms.

1. Use of the Site
PostOnce is a social media crossposting and publishing automation platform. The Service helps creators, teams, and businesses connect social media accounts, create or schedule content, configure workflows, and publish or crosspost content to supported platforms such as Instagram, TikTok, YouTube, Facebook, LinkedIn, X, Threads, Bluesky, and Pinterest, as well as other services we may support in the future. You may use these features directly in PostOnce or through supported API clients, MCP clients, ChatGPT, and other AI assistants or integrations.

You may use PostOnce only for lawful purposes and in accordance with these Terms, our Privacy Policy, and the rules, terms, and developer policies of any third-party platform you connect.

2. Accounts and Connected Platforms
You are responsible for maintaining the security of your PostOnce account and any connected social media accounts. You authorize PostOnce to use the access tokens and permissions you grant solely to provide the Service, including publishing, scheduling, syncing, adapting, and managing content according to your settings.

You are responsible for the content you submit, schedule, publish, crosspost, or import through PostOnce. You must have all rights, permissions, licenses, and consents required to use that content and to publish it to the platforms you select.

When you connect PostOnce to ChatGPT, another AI assistant, an MCP client, or another external client, requests sent through that authenticated connection are treated as instructions from you or an authorized user of your account. You are responsible for reviewing the requested destinations, content, timing, and other settings before authorizing or confirming actions that may publish, schedule, edit, or delete content.

3. Acceptable Use
You agree not to use PostOnce to:
- Violate any law, regulation, intellectual property right, privacy right, or third-party platform rule.
- Publish spam, deceptive content, malware, phishing links, or content intended to manipulate platform systems.
- Harass, impersonate, defame, threaten, or exploit others.
- Attempt to bypass platform rate limits, security controls, or access restrictions.
- Reverse engineer, copy, resell, sublicense, or misuse the Service except as expressly permitted.
- Use PostOnce in a way that may damage, disable, overload, or impair the Service.

4. Third-Party Platform Terms
PostOnce integrates with third-party social platforms and APIs. Your use of those platforms remains governed by their own terms, policies, and API rules. We are not responsible for changes, outages, restrictions, rejected posts, account actions, API limits, or other decisions made by third-party platforms.

PostOnce may also be accessed through third-party AI assistants, applications, or MCP clients. Your use of those products is governed by their own terms and privacy policies. PostOnce is not responsible for how those providers process your conversations, prompts, files, or other information before or after they send a request to PostOnce.

5. Subscriptions, Billing, and Refunds
Paid plans are billed through our payment provider. By subscribing, you authorize us and our payment provider to charge your selected payment method for recurring fees, taxes, and applicable charges.

Unless otherwise stated at checkout, subscriptions renew automatically until cancelled. You can cancel future renewals through your account settings or by contacting support@postonce.to. We may offer free trials, limited free usage, discounts, or refunds at our discretion or as stated on the pricing page at the time of purchase. Features, connected-account limits, publishing limits, API or integration access, and other usage may depend on your current plan. Continued use beyond an applicable trial or free allowance may require a paid subscription.

If you are not satisfied, you can request a full refund within 7 days of a payment by emailing support@postonce.to.

6. Ownership and License
PostOnce and its software, design, branding, documentation, and related intellectual property are owned by PostOnce or its licensors. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service according to these Terms.

You retain ownership of the content you submit to PostOnce. You grant PostOnce a limited license to host, process, modify, adapt, transmit, and publish that content only as needed to operate the Service and perform the actions you request.

7. Privacy
Our Privacy Policy explains how we collect, use, store, and protect personal data, OAuth tokens, submitted content, and platform data. You can read it at https://postonce.to/privacy-policy.

8. Service Availability and Changes
We work to keep PostOnce reliable, but we do not guarantee uninterrupted, error-free, or permanently available access. Features may change, be limited, or be discontinued as the product evolves or as third-party platform APIs change.

9. Termination
You may stop using PostOnce at any time. We may suspend or terminate access if you violate these Terms, create risk for PostOnce or other users, fail to pay required fees, or use the Service in a way that could violate platform rules or legal obligations.

After termination, we may delete or retain account data as described in our Privacy Policy and as required for legal, security, billing, or compliance purposes.

10. Disclaimers
PostOnce is provided "as is" and "as available." We do not guarantee that posts will publish successfully, that platform reach or engagement will improve, or that connected third-party services will remain available. You are responsible for reviewing scheduled and published content.

11. Limitation of Liability
To the maximum extent permitted by law, PostOnce will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, loss of data, social account restrictions, failed posts, or loss of goodwill arising from your use of the Service.

12. Changes to These Terms
We may update these Terms from time to time. If changes are material, we will take reasonable steps to notify users, such as by email or in-product notice. Continued use of the Service after changes become effective means you accept the updated Terms.

13. Governing Law
These Terms are governed by the laws of Canada, without regard to conflict of law principles.

Thank you for using PostOnce!

Partner API Terms

These Partner API Terms apply in addition to the Terms above when PostOnce enables the Partner API for your account and you accept them before activating a partner plan. A "Partner" is a business that uses the PostOnce API to let its own customers ("End Users") connect social accounts and publish content from the Partner's product.

P1. Your responsibilities to End Users
You are responsible for your product, your End Users, and the content they publish through PostOnce. You must obtain any consent your End Users need to give for you to act on their behalf, show them the connect and posting choices required by each platform, and provide first-line support to them. End Users connect their social accounts through the platform's own consent screen, which identifies PostOnce; by connecting, End Users also agree to these Terms and the PostOnce Privacy Policy.

P2. Platform rules
You must follow the terms, developer policies and user-experience requirements of every platform you publish to. This includes TikTok's Content Sharing Guidelines for Direct Post: your posting screen must show the creator's TikTok nickname, let the End User choose a privacy level from the options TikTok returns with no default selected, offer comment, duet and stitch controls that respect the creator's settings, provide the commercial content disclosure controls and required consent text, and publish only after the End User explicitly confirms. YouTube uploads remain subject to the YouTube Terms of Service (https://www.youtube.com/t/terms) and the Google Privacy Policy (https://policies.google.com/privacy), which you must link to where End Users connect YouTube.

P3. Credentials and data
Keep your API keys on your servers and never expose them to End Users or browsers. PostOnce stores End Users' platform access tokens and never shares them with you. Use the data you receive through the API, including account and creator information, only to operate your product for the End User it belongs to.

P4. Review, suspension and termination
PostOnce may review how your product uses the Partner API, including your posting screens, and may suspend or end Partner API access, or disconnect End User accounts, if your use could breach these Terms or a platform's rules, or put PostOnce's platform access at risk.

P5. Billing
Partner plans are billed through our payment provider based on usage. A billable post is one piece of content successfully published to one social account; failed posts and retries are not billed. Plan prices are shown in your PostOnce dashboard before you activate a plan. You may switch plans or cancel at any time, and usage up to cancellation is billed.
