Terms of Use — CryoSim

Effective: 1 November 2026

Last updated: 2026-11-04

1. Who we are and what these terms cover

CryoSim is a proprietorship of Pradeep Kumar Prajapati, a sole proprietor in India, trading as "CryoSim" ("CryoSim", "we", "us"). CryoSim is not a registered company. Our address is Tower No 2, Flat No 213 C, DD Misty Hills, Kalamassery, Ernakulam, Kerala 682030, India. Our full contact and grievance details are on the Contact & grievance page.

These terms apply when you use cryosim.com, the web apps on it, and our Android and Windows apps (together, "the services"). By using the services you agree to them. If you do not agree, please do not use the services.

Some products have extra terms, which apply on top of these for that product: the Stox terms and disclaimer, and the written licence or order for a company (fleet) licence bought by an organisation. Where they differ from these terms, the product's own terms win for that product. How we handle your data is in our Privacy Policy. Refunds and cancellation are in our Refund & Cancellation Policy.

2. Your account

• Most of the services work without an account. Some features (syncing, paid plans, posting on Board) need a free cryosim.com account.

• Give true details and keep your sign-in safe. You are responsible for what happens under your account.

• An account is for one person. Do not share it or sell it.

• You must be 18 or older to buy a plan or product. Younger users may use the free features with a parent's or guardian's permission.

• You can delete your account at any time at cryosim.com/account.

3. Free use and paid plans

• Most CryoSim apps are free. Some offer an optional paid plan or a one-time purchase that unlocks more features. Each product page shows the price, the billing period, any free trial and what is included, before you pay.

• Plans sold on cryosim.com from 1 November 2026 include:

  • Mariner Plus — DG Exit and COLREGS paid features — ₹99 per month, with a 7-day free trial.

  • SIRE Pro "Inspection Officer" — ₹499 per month, with a 14-day free trial.

  Prices may change later; the price on the confirmation screen is the price you pay (see section 6 for price changes).

• Prices are in Indian rupees and include all taxes. CryoSim is not registered for GST (its turnover is below the registration threshold), so no GST is charged. If this changes, we will show the tax in the price before you pay.

• A free trial is offered once per person per product. Cancel before the trial ends and you pay nothing.

4. How you pay on cryosim.com

• Payments on cryosim.com are processed by our payment provider Razorpay (UPI, cards, net banking and other methods Razorpay offers). We never see or store your card, UPI or bank details.

• Monthly plans are subscriptions. When you subscribe you authorise Razorpay to charge your chosen payment method (for example a card or UPI AutoPay mandate) once per billing period, at the price shown when you subscribed, until you cancel. If the plan has a free trial, you authorise the payment method when you start the trial and the first charge is taken on the day the trial ends. Your bank may take a small verification amount when you set this up; it is returned automatically.

• One-time products are paid with a single payment. Nothing renews.

• Your plan or product is switched on as soon as Razorpay confirms the payment (or, for a trial, the authorisation).

5. Renewal, trials and cancellation

• A monthly plan renews automatically at the end of each period until you cancel.

• We remind you at least 3 days before a free trial ends and before each renewal, with the price and a link to cancel. Your bank or Razorpay may also send its own notice before each charge.

• If a renewal payment fails, Razorpay may retry it for a few days; if it still fails, the plan stops. You never owe us money for a period you did not pay for.

• You can cancel at any time from your cryosim.com account, with no cancellation fee. Your plan then does not renew and you keep its features until the end of the period you have paid for (or, during a free trial, until the trial end date). Details are in the Refund & Cancellation Policy.

6. Price changes

If we change the price of a plan you are on, we tell you on your account page (and by e-mail or notification where we can) at least 7 days before the renewal at the new price. If you do not want to pay the new price, cancel before that renewal.

7. Purchases inside our Android apps

Subscriptions bought inside an Android app (for example Aegix Premium) are sold and billed by Google Play, under Google Play's terms. You manage or cancel them in the Google Play app under Payments & subscriptions, and Google's refund rules apply (see our Refund & Cancellation Policy).

8. CryoSim points

Some apps let you earn points, for example by using an app daily or inviting friends, and use them to unlock features. Points have no cash value, cannot be sold, transferred or exchanged for money, and are not refunded. We may change how points are earned or used; points you have already spent on an unlock are not taken back.

9. Fair use

Do not:

• break the law, or use the services to harm, cheat or harass anyone;

• share a paid plan or company licence with people it does not cover;

• copy, resell or republish our question banks, courses, guides or other content;

• scrape, overload, attack, probe or reverse-engineer the services, or get around a paywall or limit;

• upload or share content you have no right to share, or content that is unlawful, obscene, hateful, misleading, that impersonates someone, or that invades someone's privacy (including intimate or morphed images of a person shared without their consent).

We may remove content and suspend or close an account that breaks these rules, and report it to the authorities where the law requires. Unless the law or a serious breach (fraud, an attack, unlawful content) stops us, we tell you first and give you a chance to respond. We remind users of these rules, and that breaking them can lead to suspension or closure of the account and be reported where the law requires, at least once every three months.

10. Your content

Content you create (notes, projects, decks, documents, posts) stays yours. You give us permission to store, copy and show it only as needed to run the services for you — for example to sync it to your other devices, or to show a shared item to the people you shared it with. Delete it, or your account, and we delete it as described in the Privacy Policy. To report content that you think is unlawful or breaks these rules, use the Contact & grievance page; the time limits within which we act are stated there.

11. What our apps are — and are not

• Maritime preparation tools (DG Exit, COLREGS, SIRE Pro, RightShip Pro, Mariners Digest and others) are study and preparation aids. They are not official publications and are not made, approved or endorsed by the IMO, the Directorate General of Shipping, OCIMF, RightShip, any flag state or classification society. They do not replace the official rules, your company's safety management system, or the judgement of the master and officers. Using them does not guarantee that you pass an exam, an inspection or a vetting.

• Health and wellness apps (for example EyeFit, MindFit, YogaSakhi) give general guidance, not medical advice. Ask a doctor about any health problem.

• Money and market tools (PaisaCalc, Stox) give estimates and information, not investment, tax or financial advice.

• Aegix helps you spot scams and security risks but cannot catch every threat.

12. Changes to the services

We improve the services all the time, and we may change or retire a feature or a free app. If we withdraw a paid feature during a period you have paid for, we refund the unused part of that period to your original payment method, as set out in the Refund & Cancellation Policy.

13. Our content

The apps, software, designs, question banks, courses and other content we make belong to CryoSim or its licensors. You may use them for your own study and work while you use the services, but not copy, resell or republish them.

14. Responsibility

• We work hard to keep the services correct and running, but we provide them "as is" and cannot promise they will always be available or error-free.

• As far as the law allows, CryoSim is not liable for indirect losses (lost profits, lost data you did not back up, or consequential loss), and our total liability to you for any claim is limited to what you paid us in the 12 months before the claim.

• Nothing in these terms takes away rights you have under the Consumer Protection Act, 2019 or any other law that cannot be excluded by agreement.

15. Ending

You can stop using the services and delete your account at any time (deleting your account also cancels any paid plan on it). We may suspend or close an account that seriously or repeatedly breaks these terms. If we close your account for any other reason, we refund the unused part of any paid period to your original payment method.

16. Law and disputes

These terms are governed by the laws of India. Please contact us first — most problems are solved quickly (see the Contact & grievance page). You may also approach the National Consumer Helpline or a consumer commission. Subject to that, the courts at Ernakulam (Kochi), Kerala have jurisdiction.

17. Changes to these terms

We may update these terms. We change the "Effective" date above, and for changes that affect paid plans we tell you at least 7 days before they apply to you.
