Terms of Service

packdev.app · Effective date: 2026-09-26 · Version 0.2 (beta)

1. Agreement

These Terms govern your use of packdev (the "Service"), operated by Konstantin Avramenko, Serbia ("we", "us"). By creating an account or using the Service you agree to these Terms. If you use the Service on behalf of a company, you confirm you may bind it, and "you" includes that company.

2. Public beta

The Service is in public beta. It is provided free of charge, features may change or be removed, and it may contain errors or be temporarily unavailable. There is no service level agreement (SLA) during the beta. We will try to give notice of significant changes and planned downtime.

3. Accounts and workspaces

  • You must provide accurate information and keep your sign-in methods secure. You're responsible for activity under your account.
  • Data is organised in workspaces. Workspace owners and admins control membership and may remove members. Data created in a shared workspace belongs to that workspace, not to the individual member who created it.
  • The Service is designed for professional use in packaging engineering. If you use it outside your trade, business or profession, you are a consumer, and the rights that consumer law gives you apply in full whatever else these Terms say.
  • You must be at least 16 years old to create an account.

4. Acceptable use

You agree not to:

  • attempt to access other users' data, probe or break our security, or bypass rate limits or bot protection;
  • use automated means to create accounts or request sign-in codes;
  • overload the Service, or use it to send spam or harass others;
  • resell or sublicense the Service, or use it to build a competing product by copying it;
  • use the Service in violation of applicable law.

We may suspend or terminate accounts that breach these rules.

5. Your data

  • You own your data. Inputs, projects and reports you create remain yours (or your workspace's).
  • You grant us a limited licence to host, process and display your data only to provide and secure the Service.
  • We do not use your data to train machine-learning models and do not sell it.
  • We may use aggregated, anonymous usage statistics (that cannot identify you or your company) to improve the Service.
  • You can export or delete your data at any time; see the Privacy Policy.

6. Engineering disclaimer

packdev provides engineering estimates for decision support. It is not a certified calculation, a substitute for professional engineering judgement, or a substitute for physical testing.

Results depend on the inputs you provide and on the models and assumptions used (for example, compression-strength estimates, stacking patterns and load distribution). Before relying on any result — in particular for load safety, transport, storage or stacking of goods — you are responsible for verifying it against your own data, applicable standards, and testing. Each report states the algorithm version that produced it.

7. Plans, promo codes and Early Adopter Pro

7.1 Promo codes. Codes are personal, single-use and non-transferable unless the code is expressly issued for passing on (see 7.4). Codes have no cash value. We may revoke a code or the benefit obtained with it in case of abuse, resale, or a breach of these Terms.

7.2 Early Adopter Pro ("lifetime"). If you redeem an early-adopter code, you receive the Pro plan at no charge for as long as the Service is offered, subject to these conditions:

  1. It covers the features of the Pro plan as that plan is defined from time to time. It does not include features of team or enterprise plans (for example, SAML single sign-on, SCIM provisioning, organisation-wide audit exports) or paid add-ons.
  2. It is tied to you as an individual user, not to a workspace or company. If your company buys a team plan, your personal benefit continues, but it does not extend to other members.
  3. It is subject to fair use and these Terms. It may be revoked for abuse, sharing of the account, or a material breach.
  4. It is not a commitment that the Service will continue to operate. If we discontinue the Service, we will give at least 30 days' notice and a way to export your data; no compensation is owed.

7.3 Time-limited codes. When a time-limited plan ends, your account moves to the Free plan. Your data is kept. We may offer founding-member pricing for paid plans.

7.4 Referral codes. After the beta, early adopters may receive (a) a colleague code giving one other person the Pro plan for a limited period, and (b) a company code giving a discount on a team plan for a limited period. The period and discount are stated with the code. Each code works once.

7.5 Paid plans. There are no paid plans during the beta. Paid plans, if introduced, will be subject to additional terms presented before purchase.

8. Availability and changes

We may modify, suspend or discontinue parts of the Service — for example to fix a security problem, to comply with the law, to replace a component we no longer operate, or to improve how a calculation works. For changes that materially reduce what the Service does for you, we will give reasonable advance notice by email.

We may update these Terms where the law changes, where the Service changes, or where we introduce paid plans. We will tell you what is changing at least 14 days before it takes effect. If you do not accept the change, you may close your account before it takes effect and export your data; that costs you nothing. If you keep using the Service after the change takes effect, the updated Terms apply to you.

9. Intellectual property

The Service, including its software, algorithms, design, illustrations and brand, belongs to us. These Terms don't grant you any rights to it other than the right to use the Service. Feedback you send may be used freely to improve the Service.

10. No warranty

To the extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, including fitness for a particular purpose, accuracy of results, or uninterrupted operation. This Section is subject to Section 11.1: if you use the Service as a consumer, it does not affect the statutory rights your national law gives you.

11. Limitation of liability

11.1 Consumers. If you use the Service as a consumer, nothing in Sections 10 and 11 limits or excludes: our liability for death or personal injury caused by our negligence; our liability for fraud or fraudulent misrepresentation; your statutory rights to have a digital service supplied in conformity with the contract, and the remedies your national law gives you if it is not; or any other liability that the law of your country of residence does not allow to be limited. The cap in Section 11.3 does not apply to you.

11.2 Business users. To the extent permitted by law, we are not liable for indirect, incidental or consequential damages, loss of profits, loss of goods, or damage arising from reliance on calculation results (see Section 6).

11.3 Cap (business users). Our total liability to a business user for any claim relating to the Service is limited to the greater of the amounts you paid us in the 12 months before the claim or EUR 50.

11.4 Nothing in these Terms limits liability that cannot be limited by law, including for intent or gross negligence.

12. Termination

You can stop using the Service and delete your account at any time. We may suspend or terminate your account for a material breach of these Terms. We may also terminate your account, or discontinue the Service, on at least 30 days' notice — but not in order to withdraw a benefit you have already been granted under Section 7 while the Service continues to operate. On termination you may export your data during the notice period (except where the account is terminated for abuse).

13. Governing law and disputes

13.1 Governing law. These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by the laws of the Republic of Serbia.

13.2 Consumers keep their own law. If you use the Service as a consumer — that is, for purposes outside your trade, business, craft or profession — clause 13.1 does not deprive you of the protection of any rule of the law of the country in which you are habitually resident that cannot be derogated from by agreement. Where such a rule gives you more than these Terms do, that rule applies.

13.3 Business users. If you use the Service in the course of your trade, business or profession, or on behalf of an organisation, the courts of Belgrade, Republic of Serbia, have exclusive jurisdiction over any dispute arising out of or in connection with these Terms or the Service.

13.4 Consumers — where to sue and be sued. If you use the Service as a consumer, you may bring proceedings against us either before the courts of the Republic of Serbia or before the courts of the country in which you are resident, at your choice. We may bring proceedings against you only before the courts of the country in which you are resident. Clause 13.3 does not apply to you.

13.5 Talking to us first. Before starting proceedings, please write to support@packdev.app. We aim to answer complaints within 15 days and to settle them directly. This is not a precondition to any legal right you have.

13.6 Out-of-court dispute resolution. We are not currently committed to, and do not participate in, any alternative dispute resolution scheme. If you are a consumer resident in the European Union, you may still turn to the consumer dispute resolution body competent in your country. If you are a consumer resident in Serbia, you may turn to a body for the out-of-court settlement of consumer disputes from the list kept by the Serbian ministry responsible for trade.
