Terms of Use

English · Last updated: 9 September 2026

Penguin Research provides cryptocurrency market information and tools for organizing personal research. These terms apply to oldlining.com and preview.oldlining.com. By using the website, you agree to use it within the scope described below.

Research information

The website is for information and research. Its data, charts, filters and observations are not personalized investment advice, an offer to trade, or a promise of returns. Data may be delayed, incomplete, unavailable or incorrect. A missing value does not mean zero, and a returned set of records may cover only part of the market or a limited period. Consider the displayed object, time and coverage when using a result, and make your own decisions.

Penguin Research does not execute trades, take custody of assets or request transaction signatures. Following a wallet or saving a project records a research interest; it does not place an order or authorize a transaction. Do not submit passwords, private keys or recovery phrases in notes or support messages.

Accounts and saved records

Public pages do not require an account. Google sign-in and email verification provide access to personal saved features. Use an account you are authorized to access and keep your sign-in access secure. You are responsible for the material you enter; do not submit unlawful content or another person's confidential information without permission.

Use of account and personal information is described in our Privacy Policy. For account or record deletion, contact support@oldlining.com. Account deletion requests are handled through support.

Availability and acceptable use

Features and data coverage may change, and the service may be interrupted. We do not guarantee uninterrupted access or complete market coverage. When the result of a saved action is uncertain, check its status before repeating it.

Do not attempt to access another user's records, bypass access controls or interfere with the website. External links lead to services with their own terms and privacy practices; a link is not an endorsement.
