The terms.

Plain terms for a focused tool. Last updated 4 October 2026.

1. Who provides Redline PDF

Redline PDF ("we", "us") is operated from the United Arab Emirates. You can reach us at Contact Redline PDF support, and our registered name is given on request. By creating an account you agree to these terms and to the Privacy policy.

2. What Redline is

Redline is a web application for reviewing, marking up and measuring PDF drawings, with an editor, private storage for your drawings, and exports to PDF and CSV. It is a tool for professionals; you are responsible for checking any quantity, dimension or decision you take from it against the drawing and your own judgement.

3. Your account

You need an email address and a password of at least fifteen characters, and you confirm the email with a one-time code when you create the account. You must be at least 18 years old.
When you create the account you are shown a recovery code once. It is the only way to reset a forgotten password. Keep it private and safe; we cannot recover an account without it.
You are responsible for everything done with your account. Tell us at once if you believe it has been used without your permission.
One person per account. You may not share an account or resell access.

4. Trial, subscription and payment

A new account has a free trial of Redline Pro, with every tool and no card required: 30 days for an account opened on or before 31 January 2027 (the Revu 20 switch offer), and 14 days for an account opened from 1 February 2027. Each email inbox has one free trial; while the Revu 20 switch offer runs, an account whose trial has ended and that has never subscribed may restart it once, for 30 days. When the trial ends the account moves to the free plan, Redline Free, unless you have chosen a paid plan: you keep your account, your drawings and the review tools, and can keep up to three saved drawings.
There are three plans. Redline Free costs nothing. Redline Plus adds clean and editable exports, printing, page tools, the tool chest, the markup summary, revision comparison, calibrated length and area, and up to 25 saved drawings. Redline Pro adds full measurement and takeoff, building elements, CSV and estimates, editing the PDF's own content, and unlimited saved drawings. The pricing page sets out what each includes.
Subscriptions are sold by our payment partner Paddle.com, which is the merchant of record for the transaction. Paddle's checkout shows the price in your currency and any tax before you confirm, and Paddle's own terms apply to the payment itself.
Prices are stated in US dollars: Redline Plus is USD 9 per month or USD 90 per year, and Redline Pro is USD 15 per month or USD 150 per year. A subscription renews automatically until you cancel.
You can move between Plus and Pro, or between monthly and yearly billing, from your workspace. Paddle charges or credits the difference for the rest of the current period when you change.
You can cancel at any time from your workspace. Access continues to the end of the period already paid for, and nothing further is charged. Refunds are described on the Refunds and cancellation page.
We may change prices with at least thirty days' notice shown in your workspace; a change applies from your next renewal after the notice.

5. Your drawings and markups

Everything you upload or create in Redline stays yours. We claim no rights in it.
You give us permission to store and process it only as needed to provide the service to you: to save it, encrypt it, show it back to you, and produce your exports.
You are responsible for having the right to upload what you upload. Do not use Redline for anything unlawful, for anything that infringes another person's rights, or to attack the service or other accounts.
Each workspace holds up to 2 GB, with drawings up to 300 MB each and up to 100 saved checkpoints per drawing.

6. Availability and backups

We work to keep Redline available and your data intact, and we keep encrypted backups, but we do not promise uninterrupted service. Keep your own copies of anything important: the workspace lets you download any drawing at any time, and the editor can keep a copy on your own disk.

7. Ending an account

You can delete your account from the workspace at any time. Your sessions end immediately; your drawings are kept, encrypted, for thirty days in case the deletion was a mistake, then erased for good. Within those thirty days you can ask us to restore the account.
We may suspend or close an account that breaks these terms or puts the service or other users at risk. If we close an account for any other reason we will give you thirty days to download your drawings.

8. Liability

Redline is provided as it is. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability to you for any claim is limited to the amount you paid for the service in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law, and nothing here affects the statutory rights you have as a consumer.

9. Changes to these terms

If we change these terms in a way that matters, we will show a notice in your workspace at least thirty days before it takes effect. Continuing to use Redline after that date means you accept the change; if you do not, you can cancel and download your drawings.

10. Governing law

These terms are governed by the law of the United Arab Emirates, and any dispute is subject to the courts there — without prejudice to any mandatory consumer protection you enjoy where you live.
