Terms of Service

What the service does

SYNAIRGY.AI (Crosspost Engine) lets you upload videos, select connected accounts, publish immediately or on a schedule, and receive a report of the result. It currently supports Telegram, Facebook Reels, Instagram Reels, Threads, TikTok, YouTube Shorts and LinkedIn personal profiles. Other platforms may be added separately.

Accounts and access

Connect only channels and accounts that you are authorised to manage. Instagram Reels requires a professional Business or Creator account. TikTok uses official sign-in and may limit publishing settings, visibility and video duration. The service does not receive your passwords. YouTube connects through Google; Shorts must be square or vertical and up to three minutes long. Choose Public, Private or Unlisted before uploading. Facebook Reels supports managed Pages only; personal profiles are not supported. Videos must be vertical 9:16 and between 4 and 60 seconds long. LinkedIn uses official sign-in and supports personal profiles with Public video posts. Company Pages are not yet supported. LinkedIn requires an MP4 between three seconds and 30 minutes long, up to 20 MB. Reconnect the profile when access expires. Threads uses official sign-in and is available to app testers while Meta review is pending. It supports selected videos up to five minutes and 20 MB, with a shared caption up to 500 characters.

The service uses YouTube API Services to connect accounts and upload to YouTube. When using these features, you must also comply with the YouTube Terms of Service.

Your responsibility for content

You are responsible for your videos, captions, music, trademarks, advertising claims and all necessary rights and consents. Do not publish content that is illegal, misleading or violates the rules of the selected social network.

When publishing to TikTok, you must accurately disclose commercial content, your own brand or a third-party brand, and confirm compliance with TikTok’s music rules.

Scheduling and delivery

The service aims to publish at your selected time, safely retries temporary errors and reports the outcome in Telegram. Social networks may delay processing, reject videos, change their APIs or revoke access. Exact publishing times and successful external delivery therefore cannot be guaranteed.

If a provider’s response leaves the outcome uncertain, the system marks the task as needing attention instead of automatically sending the video again, to avoid duplicates.

Suspension of access

Access may be limited if you try to bypass safeguards, publish prohibited content, violate other people’s rights or place excessive load on the service. You can disconnect an individual network or request deletion of your workspace at any time.

Plans, limits and payments

New workspaces require an active subscription to connect accounts and publish. The current price, billing period and applicable taxes are shown on Stripe’s secure page before confirmation. The service does not automatically upgrade you to a more expensive plan.

The publishing allowance is counted by content item: one video counts once, regardless of the number of selected destinations. Automatic or manual retries of the same delivery do not use another allowance. Cancelling before delivery starts releases the reserved post back to your allowance.

Downgrading does not delete existing data or connections. If you exceed the new limit, new actions may be paused until usage falls, a new period begins or you change your plan. After a failed payment, a limited grace period may be available to update your payment method.

Data and deletion

Data processing is described in the Privacy Policy. Instructions for disconnecting accounts and deleting all data are on the data deletion page. You delete posts already published directly in the relevant social network.

Changes and contact

These terms may be updated when features, legal requirements or platform rules change. The date of the current version is shown at the top of this page. For service questions, contact us through the @SynairgyCrosspostBot.
