These Terms of Service (the “Terms”) govern your access to and use of SoapCalc, the soap formulation and production software available at soapcalc.app, including the public soap calculator, the public Recipe Database and the account-based workspace (together, the “Service”). “SoapCalc”, “we”, “us” and “our” refer to the provider of the Service; “you” refers to the person or organisation using it. Please read these Terms carefully, in particular sections 3 (calculations and safety), 6 (price changes), 13 (disclaimer of warranties) and 14 (limitation of liability).
1. Acceptance of these Terms
By creating an account, ticking the box that confirms you have read and agree to these Terms, or otherwise accessing or using the Service, you agree to be bound by these Terms and acknowledge our Privacy Policy. If you do not agree, do not use the Service.
You must be at least 18 years old and legally able to enter into a binding contract to use the Service. If you use the Service on behalf of a business or other organisation, you confirm that you are authorised to accept these Terms on its behalf, and “you” then also means that organisation.
2. The Service
SoapCalc is a web-based soap formulation and production workspace. It combines a public NaOH/KOH soap calculator and public Recipe Database with an account-based workspace for saved recipes, ingredients and inventory, production batches and curing, costing and pricing, labels and related production records. The features and limits available to you depend on your plan, as described on our Features and Pricing pages.
3. What the Service is not: calculations and safety
Lye amounts, SAP values, fatty-acid profiles, quality scores, costing and pricing figures, label drafts and every other output of the Service are provided for information and organisational purposes only. They depend on the data you enter and on reference values that may differ from the actual materials you use, and they may contain errors.
SoapCalc is not a laboratory, a safety assessor, a regulatory consultant or a certification body. Nothing in the Service is chemical, safety, legal, regulatory or other professional advice, and nothing in the Service certifies that a formula or product is safe, compliant or fit for sale.
You alone are responsible for:
- checking every input and output before you rely on it, including lye and water amounts;
- the safety of your formulas and of every product you make, test, sell or give away;
- the safe handling, storage and use of sodium hydroxide (NaOH), potassium hydroxide (KOH) and other hazardous materials, including protective equipment, ventilation and first-aid preparedness;
- the accuracy of your labels, ingredient lists, warnings, batch records and any claims you make about your products;
- complying with the cosmetic, consumer-product, labelling, chemical-safety, tax and other laws that apply where you make or sell products (for example, Regulation (EC) No 1223/2009 on cosmetic products in the European Union, or the Federal Food, Drug, and Cosmetic Act and the Modernization of Cosmetics Regulation Act of 2022 in the United States), including any required safety assessments, notifications and registrations.
Our Safety page and guides are general educational content and are not a substitute for proper training, testing and professional advice.
4. Accounts
- Provide accurate and complete registration information and keep it up to date.
- Keep your password confidential and use a strong password that you do not use elsewhere. You are responsible for all activity under your account.
- Tell us immediately at [email protected] if you suspect any unauthorised use of your account or any other security incident.
- An account is for one person. Do not share your login credentials; each person who uses the Service needs their own account.
- If you sign in with Google, we receive the name, email address and account identifier that Google shares with us, and your use of Google sign-in is also subject to Google's own terms.
5. Plans, trials and billing
Plans. The Service offers a Free plan and paid subscription plans. The current plans, their features and limits, and their prices are shown on our Pricing page and at checkout. Paid plans are billed monthly or annually, as selected at checkout.
Merchant of record. Paid plans are sold through our reseller and merchant of record, Paddle.com Market Ltd (“Paddle”). Paddle is the seller of record for your purchase and handles checkout, payment processing, invoicing, sales tax and VAT, and payment-related customer service. When you buy a paid plan you also enter into an agreement with Paddle under its buyer terms (Paddle Buyer Terms). We do not receive or store your full card details.
Automatic renewal. Subscriptions renew automatically at the end of each billing period for the same period, at the price that applies to your subscription at that time (see section 6), until you cancel. By subscribing, you authorise Paddle to charge your chosen payment method for each renewal.
Trials. Paid plans start with a 30-day free trial. A payment card is required to start the trial; you enter it at checkout. The first payment is taken on day 30, at the price shown at checkout, and the subscription then renews automatically. You can cancel at any time before day 30 and you will not be charged. Accounts that received an earlier trial without payment details keep it until it ends, after which the account returns to the Free plan unless you buy a paid plan.
Cancellation. You can cancel a paid plan at any time from the billing page in your account or by emailing [email protected]. Cancellation takes effect at the end of the current paid period: you keep paid access until then and are not charged again.
Failed payments and downgrades. If a renewal payment fails, Paddle may retry it, and we may move your account to the Free plan until payment succeeds. When your account moves to a lower plan, features and limits of the higher plan stop applying; your data is not deleted because of a downgrade.
6. Price changes
Price changes.We may change our prices at any time. A price published on our pricing page applies to new purchases from the moment it is published; the price shown at checkout is the price you pay for that purchase. For an existing subscription, a new price applies from your first renewal after we have given you at least 30 days' notice by email or in the app. If you do not accept the new price, you can cancel before it takes effect; keeping your subscription after it takes effect means you accept it. Taxes, currency conversion and fees charged by your bank or card issuer are not part of our price and may change independently. Promotional or introductory prices apply only for the period stated.
7. Refunds
Refunds are handled as described in our Refund & Cancellation Policy, which forms part of these Terms, and are issued through Paddle to your original payment method. Nothing in these Terms limits any refund, withdrawal or cancellation right you have under applicable consumer law or under Paddle's buyer terms.
8. Acceptable use
You must not, and must not help anyone else to:
- use the Service in breach of any law or regulation, or to store or share unlawful, infringing or harmful material;

You give us a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, display and transmit Your Content only as needed to operate, secure, support and improve the Service and as you instruct us.
Public recipes. If you publish a recipe to the public Recipe Database, you also allow us to display it publicly and allow other users to view, save, print and adapt it. You can unpublish a recipe at any time; anonymised counters and moderation records may be kept so that community data stays consistent.
Your responsibility.You confirm that you have the rights needed to submit Your Content and that it does not infringe anyone else's rights or break any law.
Export and privacy. You can export your account data from the Service or request a copy from support. Keep your own copies of important records. How we handle personal data is described in our Privacy Policy and Cookie Policy.
10. Intellectual property
The Service, including its software, design, databases, text, guides, graphics and the SoapCalc name and logo, belongs to us or our licensors and is protected by intellectual property laws. Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to use the Service for your own personal or internal business purposes while your account is active. All rights not expressly granted are reserved.
If you send us feedback, ideas or suggestions, we may use them freely and without any obligation to you.
11. Third-party services
The Service works with services provided by third parties, such as payment processing by Paddle, sign-in with Google, links to marketplaces such as Etsy, and optional integrations you choose to connect. Those services are governed by their own terms and privacy policies. We do not control them and are not responsible for their content, availability, changes or acts and omissions, and an interruption of a third-party service may affect features of the Service that depend on it.
12. Availability and changes to the Service
We work to keep the Service available and secure, but we do not guarantee that it will be uninterrupted, timely or error-free. The Service may be unavailable during maintenance, updates or events outside our control.
We develop the Service continuously and may add, change or remove features. If we make a change that materially reduces a paid feature, we will tell you in advance by email or in the app, and you may cancel your subscription. If we discontinue the Service entirely, we will give at least 30 days' notice so that you can export your data.
13. Disclaimer of warranties
To the fullest extent permitted by law, the Service and all content and outputs are provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory, including implied warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement and uninterrupted availability. This does not affect any warranty or guarantee that cannot be excluded under the law that applies to you.
14. Limitation of liability
To the fullest extent permitted by law:
- we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, business, goodwill, data or products, arising out of or related to the Service or these Terms, even if we were told such damages were possible;
- our total liability for all claims arising out of or related to the Service or these Terms is limited to the amount you paid for the Service in the 12 months before the event giving rise to the claim.
Nothing in these Terms excludes or limits liability for wilful misconduct, gross negligence or fraud, for death or personal injury caused by negligence, or any other liability, including consumer rights, that cannot be excluded or limited under applicable mandatory law.
15. Indemnity
To the extent permitted by applicable law (including mandatory consumer-protection law), you will indemnify and hold us harmless from any third-party claim, and the related losses, damages and reasonable costs (including legal fees), arising from your breach of these Terms, Your Content, or the products you make, label or sell using the Service.
16. Termination
By you. You can stop using the Service at any time and close your account by emailing [email protected] from your account email address. Cancel any paid subscription first so that it does not renew (section 5).
By us. We may suspend or close your account, with notice where reasonable, if you breach these Terms, if we are required to do so by law, if your use creates a security, legal or operational risk for us or other users, or if payment for a paid plan cannot be collected.
Effect. When your account is closed, your right to use the Service ends. We may delete Your Content after a reasonable period, subject to our legal retention obligations, so export anything you need before closing your account. Sections 3, 9 (as regards published recipes and your responsibility for Your Content), 10, 13, 14, 15, 18, 19 and 20, and any payment obligations that have already arisen, survive termination.
17. Changes to these Terms
We may update these Terms from time to time. We will notify you of material changes at least 30 days before they take effect, by email or in the app. When a new version takes effect, we will ask you to accept it the next time you use your account; if you do not agree, you can stop using the Service and close your account before the new version applies. Changes that are not material (for example, clarifications or corrections) take effect when published. The version and date at the top of this page show which version is current.
18. Governing law and disputes
These Terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws rules. The courts and enforcement offices of the Republic of Türkiye have jurisdiction over any dispute arising out of or related to these Terms or the Service.
If you are a consumer, you may also apply to the consumer arbitration committees and consumer courts competent under Turkish Consumer Protection Law No. 6502, and nothing in these Terms deprives you of the protection of the mandatory consumer laws of the country where you live, or of your right to bring proceedings there.
19. General provisions
- Entire agreement.These Terms, together with the Privacy Policy, the Refund & Cancellation Policy, the Community Rules and any terms shown at checkout, are the entire agreement between you and us about the Service.
- Severability. If any provision is found invalid or unenforceable, it will be limited to the minimum extent necessary and the rest of these Terms remains in effect.
- No waiver. Our failure or delay in enforcing a provision is not a waiver of our right to enforce it later.
- Assignment. You may not transfer your rights or obligations under these Terms without our written consent. We may transfer them in connection with a merger, acquisition or sale of all or part of our business, provided your rights are not reduced.
- Force majeure. We are not responsible for delays or failures caused by events beyond our reasonable control, such as natural disasters, power or internet outages, failures of third-party services, acts of government, war or labour disputes.
- Notices. We send notices to the email address on your account or in the app. You can send notices to [email protected].
