Trinka’s referral program is a great way for you to share the benefits of our services with your friends, family members, or any other acquaintances. By referring them to Trinka, you not only help them discover a useful platform but also earn discounts on your subscription purchases. Please refer to the below guidelines for more details:

Eligibility Criteria:

a) Eligibility to be a Referrer:

To qualify as a referrer for Trinka, you must:

  • Have a Trinka account.
  • Not be an organizational user, meaning your account should not be upgraded through a special plan associated with an institution. For instance, if your university or organization has a subscription to Trinka, you cannot use your organizational or university email ID to refer friends.

b) Eligibility to be a Referee:

To qualify as a referee, you must:

  • Be a new user or a current user who has never purchased any Trinka paid plans such as Trinka Premium/ Premium Plus or be part of any institutional or enterprise plans.
  • Have not purchased any Trinka credits.

Definition of a Successful Referral:

A referral is considered successful when the referee uses a coupon code shared by the referrer to successfully complete a purchase of a Trinka subscription.

How to Participate in the Referral Program:

To join the referral program, please follow these steps:

Step 1: Share your unique referral coupon with a referee, who could be a friend, family member, colleague, or anyone else in your network. You can make an unlimited number of referrals. You will receive rewards for each successful referral.

Step 2: When the referee uses your unique referral coupon to purchase a subscription, they will receive a 10% discount on the subscription price. For example, if the referee buys a plan worth $125, they will apply your coupon code at checkout to receive an instant discount of $12.5, thus only needing to pay $112.5. Note that each referee can use the referral coupon only once. You may refer multiple referees, but each can use your coupon code only once.

Step 3: Once the referee completes their purchase using your unique referral coupon, you will receive a referral reward worth 10% of their purchase amount. For instance, if the referee purchases a plan worth $125, you will receive a reward of $12.5 in your Trinka account.


When the referee purchases a subscription plan on Trinka using the unique referral coupon you shared, you will receive rewards worth 10% of the purchase amount. This will be added to your Trinka account as Referral Rewards which can be used in the following ways:

  • To purchase a Trinka subscription.
  • To upgrade your existing Trinka subscription.
  • It will be automatically applied on the renewal of your existing subscription.


Below are some of the guidelines regarding the restrictions on participating in the referral program:

  • Referral coupons can be used only once per user. While you can refer as many people as you wish, each referee can only use the coupon once.
  • Once a user has used a referral coupon for a discount, other referral coupons cannot be applied to their account.
  • Referral rewards and coupons apply solely to subscription purchases.

A Fair Use Policy, limiting the total monthly usage of language check to 150,000 words and plagiarism checks to 120 scans is applicable. The limits may change in the future. Any changes will be disclosed in the terms.

Refunds are not allowed for purchased subscriptions. Once you purchase a subscription, you can cancel it whenever you wish to avoid getting charged for the renewal of the subscription. When you cancel your subscription, the subscription continues till the end of the period you purchased it for.

You can move from a shorter subscription period to a longer subscription period (for example, monthly to yearly Trinka subscription); in such cases, the amount to be paid by you for the new subscription will be adjusted to subtract the remaining amount of the current subscription.

You can cancel your subscription from your account settings. For any support, just email us at support@trinka.ai.
