Terms of Service

These terms govern your use of Castfrom (“the Service”), provided by Social Marketing Inc., Bunkyo-ku, Tokyo, Japan (“we”, “us”). By creating an account or connecting a social media account you agree to them.

1. The Service

Castfrom lets you connect social media accounts that you own or are authorised to manage, publish content to them, and view performance metrics for that content. Castfrom works through the official APIs of X, TikTok, Instagram, Threads and YouTube. What each network allows can change, and features may be added, limited or withdrawn as a result.

2. Accounts and eligibility

• You must be at least 18 years old and, if acting for an organisation, authorised to bind it.
• Anyone meeting that requirement can create a workspace from the sign-up page. We email a link to confirm the address, and the workspace is created when you open it. You choose an account ID and we issue an access key once, at that moment. We store only a hash of it and cannot read it back, so keep it somewhere safe; if you lose it, write to us from the email address on your workspace and we will issue a new one.
• You are responsible for keeping your Castfrom login secure and for everything done through it.
• You may only connect social media accounts that you own or that you have explicit permission to manage.

3. Your content

• You keep all rights to the content you publish through Castfrom. You grant us only the licence needed to store it, show it to you and your workspace, and transmit it to the networks you selected.
• You are responsible for the content you publish, including having the rights to any media and music it contains, and for its compliance with the law and with each network’s rules.
• You review each post and its settings before publishing. Castfrom publishes only what you approved, to the accounts you selected.

4. Acceptable use

You agree not to use Castfrom to:

• publish spam, misleading content, or the same content to many accounts in a way that violates a network’s rules;
• publish content that is unlawful, infringing, harassing or otherwise prohibited by the network it is published to;
• access accounts or data you are not authorised to access, or attempt to circumvent a network’s limits or policies;
• scrape, resell or redistribute data obtained through the Service;
• reverse engineer or interfere with the Service.

5. Platform terms

Your use of each network through Castfrom is also subject to that network’s terms and developer policies, including the YouTube Terms of Service, the TikTok Terms of Service, the Instagram Terms of Use, the Threads Supplemental Terms and the X Terms of Service. If a network suspends or limits Castfrom’s access, the affected features may stop working and we are not liable for that.

6. Privacy

How we handle data is described in the Privacy Policy, which forms part of these terms.

7. Plans, fees and payment

Castfrom is free while it is in beta. Paid plans start after the beta; we will notify every workspace in the application and by email at least 30 days before any charge applies, and nothing you do during the beta commits you to a paid plan. The plans, add-ons, AI-credit packs and their prices are listed on the pricing page, which forms part of these terms.

7.1 Payment and the reseller

• Paid plans and credit packs are sold through Stripe’s Link service, which acts as the reseller and merchant of record for the payment, collects any sales tax, VAT or GST due in your country, and appears on your statement as LINK.COM* CASTFROM. Link’s own terms apply to the payment itself. Where Link does not act as the reseller (for example, sales to customers in Japan), Social Marketing Inc. is the seller.
• Prices are in US dollars and exclude tax. The tax for your country is shown and added at checkout.

7.2 Subscriptions and renewal

• Plans and add-ons are subscriptions that renew automatically at the end of each period (monthly or yearly) at the price then in effect, until you cancel. We email you at least 7 days before a yearly plan renews.
• You can cancel at any time from Plan and billing in the application or from your Link account. Cancellation takes effect at the end of the current paid period; until then you keep the plan, and afterwards the workspace returns to the Free plan without deleting your data.
• Moving to a higher plan takes effect at once and the difference for the rest of the period is charged. Moving to a lower plan takes effect at the next renewal of the plan; until then you keep the plan already paid for. Reducing an add-on stops its charge from that add-on’s next renewal, and what was paid for stays available until then.
• If your plan comes to allow fewer brands than your account has (after moving to a lower plan, reducing extra brands, or a plan ending), you choose which brands stay active; if you do not, your first brand and then the oldest ones stay. The other brands become read-only: nothing new can be posted or scheduled from them and their scheduled posts are held, while their data is kept for 90 days. Moving to a plan that allows them restores them as they were; after 90 days we may delete their data. If a payment fails, we and our payment provider may retry it. If it still fails, the workspace returns to the Free plan. Posts already scheduled are not deleted, but new scheduling beyond the Free plan’s limits is paused.
• We will announce price changes at least 30 days in advance. A new price applies from your first renewal after that date.

7.3 AI credits

• AI credits are units for using Castfrom’s AI features and for paying the fee on ad boosts. They are not money, have no cash value, cannot be transferred or exchanged, and are not refunded when unused.
• Credits included with a plan are granted for each billing month and expire at its end. Purchased credits expire 6 months after the date of purchase.
• An AI feature uses credits according to the processing it actually performs. The application shows the expected amount before you start and records every use in the credit history.
• The ad boost fee is a percentage of the ad spend stated on the pricing page and is paid only from purchased credits. It is charged on the whole budget when you approve the boost, converted to US dollars at the exchange rate of that moment (the rate and its source are recorded with the boost); when the boost ends, the fee on any budget the network did not spend is returned as credits at the same rate. Ad spend itself is charged by the advertising network to your own ad account.
• Some network actions cost Castfrom money per use. Where the pricing page says so (for example, a post with a link on X), that action uses the stated number of credits.

7.4 Refunds

Because the Service is digital and available as soon as you pay, payments are not refundable, including the unused part of a period and unused credits, except where a refund is required by law (including any right of withdrawal you have under the law of your country) or our payment provider decides to issue one under its own policies. If a credit pack is refunded, the credits remaining from it are removed. If a plan payment is refunded, the plan ends at once and the AI credits for that month are removed. After any refund, AI features, videos and purchases are not available on the account for 30 days.

8. Availability and changes

We aim to keep the Service available but do not guarantee uninterrupted operation. We may change or discontinue features with reasonable notice. Scheduled posts may fail if a network is unavailable or rejects the content; you should check the result of each post.

9. Termination

You can stop using Castfrom and delete your account at any time. We may suspend or terminate accounts that breach these terms or that put the Service’s platform access at risk. On termination we delete your data as described in the Privacy Policy.

10. Disclaimer and liability

The Service is provided as is. To the extent permitted by law, we are not liable for indirect or consequential loss, or for loss caused by a network’s actions, outages or policy changes. Our total liability for any claim is limited to the fees you paid for the Service in the 12 months before the claim, or JPY 100,000 if no fees were paid.

11. Governing law

These terms are governed by the laws of Japan. Disputes are subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.

12. Changes to these terms

We may update these terms. Material changes will be announced in the application at least 14 days before they take effect. Continued use after that date means you accept the new terms.
