Terms of Service

01Who we are, and this agreement

/Seiðr (also called Seidr Stack) is a software service run by Seidr Stack, a sole proprietorship based at No 60/5, 4th T Block, Jayanagar, Bengaluru 560041, Karnataka, India (“we”, “us”). These Terms of Service are the agreement between us and you, the person or the organisation you act for (“you”), when you use the website at https://seidrstack.com, the app at https://marketing.seidrstack.com, and anything else we provide under the /Seiðr name (together, the “Service”).

By creating an account, starting a plan or using the Service, you accept these terms and the policies they refer to: the Privacy Policy, Refund & Cancellation Policy, Acceptable Use Policy and Cookie Policy. If you accept for an organisation, you confirm you’re allowed to bind it. If you don’t agree, don’t use the Service.

02Who can use the Service

You must be at least 18 and able to form a binding contract. The Service is made for work: brands, businesses, freelancers and the agencies and vendors that work with them. It isn’t meant for personal or household use.

You can use the Service as Solo (one person), Teams (a team inside one brand, or a small studio) or Agency (one account serving several client brands). The account type and plan set what the account can do and how many people, brands and credits it has, as shown on the Pricing page.

03Your account

• Give accurate details and keep them current. You can sign in with Google or with an email and password; keep your password and your Google account secure.
• You’re responsible for everything done under your account, and, if you own an account with seats, for the people you invite and the roles and permissions you give them.
• Tell us straight away at support@seidrstack.com if you think someone has got into your account.
• Accounts are for the people they belong to. Don’t share a seat between several people; invite them instead.

04Plans, credits and payment

Plans

Paid plans are subscriptions billed in advance, monthly or yearly, through our payment partner Razorpay. Teams and Agency plans are priced per seat, by the seat’s band (Full, Maker or Contributor; guests are free). Extra brands beyond those your plan includes are billed as add-ons. Prices are shown in US dollars and on the Pricing page; taxes such as GST are added where the law requires.

Changes during a period

Upgrading, adding seats or adding brands takes effect straight away, and the difference for the rest of the period is charged then, as calculated by Razorpay. Moving down takes effect straight away too, and any unused difference is handled as the Refund & Cancellation Policy describes.

Credits

AI work (drafting, making outputs, media jobs) uses credits. Each plan includes credits for the month, and no more than a third of them can be used in any one week, resetting each Monday at 00:00 UTC. Included credits don’t roll over. Credit packs can be bought on top; they count towards the month they’re bought in and expire 12 months after purchase. Credits have no cash value and can’t be transferred.

Auto top-up

If you switch on auto top-up, we add a credit pack when your credits run out and put its price on your subscription’s next invoice, up to the number of packs a month you set. You can switch it off at any time from Plan & usage.

Your own tools

Media tools you connect with your own keys (such as Runway, Higgsfield, Google Veo or ElevenLabs) bill you directly, under your agreement with them. We charge only the credits shown for the work around each job.

Failed payments

If a renewal can’t be collected, Razorpay retries it. Until it’s paid, the account works with the limits of the free Solo Basic plan. Nothing you made is deleted, and paying restores the plan.

Price changes

We may change prices. A change to a plan you’re on applies from your next billing period after we’ve given you at least 30 days’ notice by email or in the app.

05Cancelling

You can cancel a paid plan at any time from Plan & usage. It stays active until the end of the period you’ve paid for, then the account moves to the free plan’s limits; nothing is deleted. Refunds are set out in the Refund & Cancellation Policy. You can delete your account and its data at any time from your Profile.

06Your content

“Your content” is everything you or your team put into the Service (websites you ask us to read, files, connected accounts’ material, briefs, notes, comments, uploads) and everything the Service makes for you (your Brand Spine and every output).

• It’s yours. As between you and us, you own your content. We claim no ownership of it.
• What you allow us to do with it. You give us a worldwide, non-exclusive licence to host, copy, process, transmit and display your content only as needed to run the Service for you, to keep it secure, and as the law requires. This ends when your content is deleted, apart from copies in backups for the short time they’re kept.
• No training on your content. We don’t use your content to train AI models.
• You have the rights. You confirm that you have the rights and permissions needed for everything you put in, including material from clients, vendors and the people in it, and for any website or account you ask us to read.

07AI-made work

The Service uses AI models from providers listed on our Subprocessors page to read your materials and draft work. AI output can be wrong, incomplete or similar to what others receive.

• Review every output before you approve, publish or send it. You decide what goes out, and you’re responsible for it.
• Check that claims, prices, offers, testimonials and comparisons are true and can be backed up, and that work meets the laws and codes that apply to you (for example consumer, advertising and data-protection law, and the ASCI Code in India).
• Where the Service can’t find proof for something, it says so and leaves it for you rather than inventing it. Treat anything marked as inferred as a draft.
• Where an output includes material from other people (fonts, photographs, music, trademarks), it’s up to you to have the right to use it.

08Connected services

You can connect other services: to read your brand’s material (for example Google Drive, Notion or Instagram), to publish (LinkedIn, Instagram, Facebook, X), to sync work (Linear, Jira), to notify (Slack), or to make media (Runway, Higgsfield, Google Veo, ElevenLabs). When you do:

• you authorise us to act on that service for you, within the access you grant, including publishing posts you book or ask us to publish;
• your use of that service is under its own terms, which you’re responsible for following;
• we aren’t responsible for those services, their availability, or changes to what they allow;
• you can disconnect at any time from Connections, and we stop using the access then.

09Clients, vendors and guests

If you use the Service for clients, or invite vendors or guests (through review links, registration links or seats), you’re responsible for having a lawful basis to share their information with us and to ask for theirs, and for what you ask of them. Where you process personal data for a client, our Data Processing Agreement applies between you and us.

Review and registration links work for anyone who has them until they expire or you revoke them; share them with care.

10Using the Service properly

Use the Service only lawfully and as the Acceptable Use Policy allows. In particular, don’t try to get around plan limits or credits, reverse engineer or copy the Service, resell access to it without our written agreement, or interfere with its security or other people’s use of it.

11Our service

We work to keep the Service available, secure and useful, and we’ll keep improving it. We may add, change or remove features; where a change takes away something important from a paid plan, we’ll tell you in advance.

Features marked as early access, beta or preview may change or stop, and are provided as they are. Support is by email at support@seidrstack.com.

12Our intellectual property

The Service, its software, design and documentation, and the /Seiðr and Seidr Stack names and marks belong to us or our licensors. These terms give you the right to use the Service while your account is active; they don’t transfer any of our rights to you. If you send us feedback or ideas, we may use them without owing you anything.

13Suspension and ending

You can stop using the Service and delete your account at any time.

We may suspend or end your access if you seriously or repeatedly break these terms or the Acceptable Use Policy, if you don’t pay, if we must by law, or if your use puts the Service or others at risk. Where we reasonably can, we’ll tell you first and give you the chance to fix it and to export your content.

When an account ends, we delete its content as the Privacy Policy describes. Sections that by their nature should survive (such as payment owed, liability and disputes) continue to apply.

14Disclaimers

Apart from what these terms expressly promise, and to the extent the law allows, the Service is provided “as is” and “as available”. We don’t promise that it will be uninterrupted or error-free, that AI output will be accurate or fit a particular purpose, or that it will bring any particular business result.

15Limits on liability

To the extent the law allows:

• neither of us is liable for indirect or consequential loss, or for lost profits, revenue, goodwill or data, however caused;
• our total liability for all claims connected with the Service in any 12 months is limited to the amount you paid us in those 12 months, or US$100 if more.

Nothing in these terms limits liability that can’t be limited by law, such as for fraud.

16Claims about your content

If someone brings a claim against us because of your content, material you asked us to read or publish, or your breach of these terms or the law, you’ll cover our reasonable costs and losses from it. We’ll tell you about the claim promptly and let you take part in handling it.

17Governing law and disputes

These terms are governed by the laws of India. Before going to court, let’s try to settle any dispute by talking: write to support@seidrstack.com and we’ll respond within 15 working days. If that doesn’t settle it, the courts at Bengaluru, Karnataka, India have exclusive jurisdiction. Consumers keep any rights their local law gives them.

18Changes to these terms

We may update these terms. If a change matters, we’ll tell you at least 30 days before it applies, by email or in the app, unless it’s needed sooner for legal or security reasons. If you keep using the Service after a change applies, the new terms apply; if you don’t agree, you can cancel before then.
