Terms of Service

Last updated: August 22, 2026

These Terms of Service (the “Terms”) govern your use of the best-in-slot website and web application (together, the “service”). By creating an account or using the service, you agree to them. How we handle your data is described in our Privacy Policy and on our Data Deletion page.

1. Who you’re contracting with

Your contract is with Göksu Yıldırım, an individual sole proprietor doing business as best-in-slot, based in Türkiye (“best-in-slot”, “we”, “us”, “our”). There is no company behind the product — you are dealing with its founder directly. For anything at all, write to [email protected].

2. Eligibility

best-in-slot is a business tool. You may use the service only if you are at least 18 years old and are using it for business or professional purposes. If you use the service on behalf of a company, you represent that you have authority to bind that company, and “you” means that company too.

3. The service

best-in-slot generates Meta ad creative — ad concepts, AI-generated images, and copy — from the website URL, brand details, logos, and product photos you provide. When you connect your Meta account and explicitly ask it to, best-in-slot creates an ad inside the ad set you choose in your own Meta ad account. Every ad is created paused by default — it goes live at creation only if you explicitly switch off “Create paused” when you publish.

best-in-slot never creates campaigns or ad sets and never touches your budgets, targeting, or schedules. Unless you explicitly choose otherwise at publish time, every ad starts paused — turning it on, and everything it spends after that, is entirely in your hands.

4. Your account

You need an account to use the service. You agree to provide accurate information, keep your login credentials secure, and not share your account. You are responsible for all activity that happens under it. Tell us promptly at [email protected] if you suspect unauthorized use.

5. Credits, plans & payments

The service runs on credits. Each generation action costs a set number of credits, shown in the product and on our pricing page, and is charged when the action starts. Credits are a metering unit, not money — they can’t be transferred to another account or redeemed for cash.

  • Free signup credits — every new account gets 50 credits, free, no card. They never expire.
  • Plans — we offer Lite at $19 per month (400 credits every month, 1 brand), Starter at $39 per month (1,000 credits every month, 1 brand), Growth at $79 per month (2,100 credits every month, 5 brands), and Agency at $169 per month (4,500 credits every month, 10 brands). Plan credits reset at each billing cycle and don't roll over. Free signup credits and top-ups never expire — and spending always uses plan credits first.
  • Brands — each plan includes a set number of brand profiles, shown on the pricing page. The cap applies when you create a new brand.
  • Top-ups — a one-time pack of 50 credits for $10, and you can buy several packs at once. Top-up credits never expire.
  • Failed generations — If a generation fails, the credits come straight back automatically. That includes generations that error out, time out, or get cut short by a deploy.

Changing plans, cancelling, failed payments

  • Cancel any time through the customer portal. Your plan runs to the end of the period you’ve paid for — you keep that cycle’s plan credits until then — and simply doesn’t renew. When it ends, remaining plan credits lapse; signup and top-up credits stay.
  • Upgrade — takes effect immediately: you pay the difference for the rest of the cycle and the extra credits arrive right away.
  • Downgrade — scheduled for your next billing date, so you keep everything you’ve already paid for. You can undo a scheduled downgrade any time before it lands.
  • Failed payment — if the payment for a renewal or a plan change fails, the change doesn’t happen. A subscription whose renewal fails goes on hold and its plan credits pause until you fix the payment method in the portal. Your permanent credits are untouched.

Payment processing — Dodo Payments

Purchases are processed by Dodo Payments, our merchant of record — an authorized reseller that sells the subscription or top-up to you, while the service itself still comes from us. In practice that means:

  • the hosted checkout, your card details, your invoices, and any applicable sales tax or VAT are handled by Dodo — card numbers never touch our systems;
  • the charge on your card statement appears under Dodo Payments’ name, not ours;
  • Dodo’s buyer terms, presented at checkout, apply to the purchase itself. Invoices and card management live in the Dodo customer portal, linked from your billing settings.

If we change prices or credit costs, the change never applies to a period you have already paid for, and we’ll give you notice before it affects a renewal. Beyond the automatic credit refunds above and your statutory rights (including section 6), fees already paid are non-refundable — but if something genuinely went wrong, email us and we’ll look at it case by case with Dodo.

6. Your 14-day withdrawal right (EU & UK consumers)

If you are a consumer in the EU or the UK, you have a legal right to withdraw from a purchase within 14 days, no reason needed. We’d rather state it plainly than bury it in “except where required by law”.

  • Subscriptions — by subscribing, you ask us to start providing the service straight away rather than waiting out the 14 days. If you withdraw within 14 days, we refund what you paid minus a proportionate amount for what was already supplied: the part of the billing period that has run and the credits you have already spent.
  • Generations are digital content — each generation is digital content delivered immediately at your request. By starting a generation, you expressly consent to immediate supply and acknowledge that you lose the right of withdrawal for that content once generation has begun.
  • Renewals — the renewal price and billing cycle are shown before you subscribe and in the customer portal. The 14-day period runs from your initial purchase; it does not restart at each renewal.

To withdraw, email [email protected] within the 14 days and we will arrange the refund with Dodo Payments, back to your original payment method. The checkout terms Dodo presents also apply to the purchase. Nothing in this section — or anywhere in these Terms — limits mandatory consumer rights in your country of residence.

7. Your content & inputs

You keep ownership of everything you give the service: website URLs and the page content we fetch from them, brand details, logos, product photos, product descriptions, and anything else you upload or type in.

You warrant that you own these things or have the right to use them — including the right to let us process them — and that they don’t infringe anyone else’s rights. You grant us a limited licence to store and process them solely to provide the service to you: building your brand profile, generating ads, and publishing to Meta when you ask. We don’t use your content to train AI models, and we don’t show it to other users. Which providers process it on our behalf — and what their own policies say — is set out in our Privacy Policy.

8. AI-generated output

The concepts, images, and copy the service produces are AI-generated. As between you and us, the output generated for you is yours, and you may use it in your advertising. Three things to understand about it:

  • It can be wrong. AI output can be inaccurate, incomplete, or a bad fit for your business. Review every ad — every claim, every image — before you run it. That responsibility is yours.
  • It may not be unique. AI models given similar inputs can produce similar output, so another user’s ads may resemble yours. We can’t guarantee uniqueness, and we make no promise that output is free of third-party rights.
  • Platform rules apply to you as the advertiser. Meta requires advertisers to follow its Advertising Standards and, in some cases, to disclose that ad content is AI-generated or digitally altered. Making those disclosures — and complying with any AI-labelling rules wherever you advertise — is your responsibility.

9. Meta platform

Your Meta ad account, and the ads created in it, are governed by your own agreement with Meta. Complying with Meta’s advertising policies is your responsibility. We do not control Meta’s ad review outcomes, ad delivery, or your ad spend, and we are not responsible for actions Meta takes on your account. You can disconnect Meta from best-in-slot at any time — see Data Deletion for what happens when you do.

Publishing to your Instagram account

If you link an Instagram account, the service can publish posts to it — one at a time when you press Publish, at a time you schedule, or automatically on a schedule you set up and switch on. Three things follow from that, and all three are yours:

  • You are the publisher. Everything that goes out appears on your profile, in your name. You are responsible for it — including anything published by a schedule you turned on, whether or not you read it first. The product offers an approval mode precisely so that nothing publishes unread unless you choose otherwise.
  • Instagram’s rules apply to you. Your account is governed by your own agreement with Meta, including its Community Guidelines and Terms of Use. We do not control how Instagram ranks, restricts, or removes what you post, or any action it takes on your account.
  • We cannot take a post down for you. Instagram’s API has no way to delete a published post. Archiving one in best-in-slot removes it from your queue here and nothing else — to remove it from your profile, delete it in the Instagram app.

10. Acceptable use

You agree not to:

  • use the service to create ads that are unlawful, deceptive, infringing, or that violate the policies of the platform they run on;
  • submit websites, brands, logos, or photos you have no right to use, or impersonate another business;
  • interfere with the service, probe or circumvent its security or credit limits, or access it by automated means outside its intended interface;
  • resell or redistribute the service without our permission.

11. Disclaimers & limitation of liability

The service is provided “as is” and “as available”, without warranties of any kind, express or implied — including fitness for a particular purpose and any warranty about the performance of the ads you generate or run. To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost profits, revenue, or data. Our total liability arising out of or relating to the service is capped at the fees you paid us in the 12 months before the event giving rise to the claim.

If you use the service as a consumer, nothing in this section limits rights or liability that your local law does not allow to be limited — including liability we cannot lawfully exclude.

12. Termination

You can stop using the service at any time. Cancelling a subscription is self-serve through the customer portal (section 5). Deleting your account is currently handled by email, not by a button in the app — the exact steps are on our Data Deletion page.

We may suspend or terminate your access if you breach these Terms, misuse the service, or where we must do so to protect the service or comply with the law — where reasonable, we’ll warn you first. If we terminate your access without cause, we’ll refund the unused portion of anything you’ve prepaid. Sections 7, 8, 11, 14, and 15 survive termination.

13. Changes to these terms

We may update these Terms from time to time. When we do, we’ll revise the “Last updated” date above — and for material changes we’ll notify you by email or in the product before they take effect. Continued use of the service after an update means you accept the revised Terms.

14. Governing law

These Terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-law rules, and any dispute will be resolved in the courts of Istanbul, Türkiye. One express carve-out: if you use the service as a consumer, this clause does not take away mandatory consumer protections of the country you live in, or your right to bring a claim in your local courts where that law gives it to you.

15. General

If any part of these Terms turns out to be invalid or unenforceable, the rest stays in force, and the invalid part is read as coming as close to its intent as the law allows. We may assign these Terms — for example to a company we incorporate, or in a merger or sale of the service — as long as your rights under them are not reduced; you may not assign them without our consent.
