Frequently Asked Questions — One Line Loop
Everything you need to know about One Line Loop. Learn about daily logs, one-line journaling, privacy, billing, and how to get started if you've never been able to keep a journal going before.
What is One Line Loop?
One Line Loop is an email‑first daily log app for keeping daily logs. One prompt each evening, click the button to write your one line, and your streak updates automatically. It's a simple way to build a daily journaling habit.
How do daily logs work with One Line Loop?
We email you a short prompt at ~8pm local time. Click the button in the email to write ≤120 characters—or reply to the email with your one line. Your daily log entry is encrypted and added to your history.
What is one-line journaling?
One-line journaling is a minimalist journaling practice where you write just one sentence each day. This constraint makes it easy to maintain a daily log habit without overwhelm. One Line Loop makes one-line journaling effortless through email prompts.
How is One Line Loop different from other journal apps?
One Line Loop is email‑first and constraint‑driven. Unlike other journal apps, it fits into your existing email routine. One prompt, click to write one line, one streak — simple by design. No complex features, just consistent daily logs.
Is my data private and secure?
Yes. When you write in the web app, your line is encrypted in the browser and stored as ciphertext. Firebase security rules ensure only your account can read your documents—other users cannot see your journal. We do not sell your entries or use them for ads. Like any hosted app, cloud infrastructure providers operate the servers; see our Privacy Policy for the full picture, including how email delivery works.
How much does One Line Loop cost?
Start with a 7‑day free trial. Then $2/month or $20/year (save 17%). Cancel anytime with no questions asked.
Do I need a card to start the 7-day trial?
Starting the subscription trial goes through Stripe Checkout, which usually asks for a payment method. You are not charged until the trial period ends for the plan you pick. You can cancel before the first charge.
What happens when my trial ends?
After 7 days, the plan you selected ($2/month or $20/year) bills automatically unless you cancel first. You can cancel anytime from your billing portal or account settings.
Can I reply by email instead of opening the app?
Yes. Each evening prompt includes a reply address. Reply with your one line (≤120 characters) from the same email on your account—no app required. Replies are encrypted like app entries when your account has encryption enabled.
Do I get evening emails before I subscribe?
Evening prompts and full app access require an active subscription. Start with a 7-day free trial via Stripe Checkout—you are not charged until the trial ends unless you cancel first.
Can I export or delete my daily log data?
Yes. You can export or delete your data from your account settings at any time. Your daily logs belong to you. We'll never lock you in.
How do I start one-line journaling?
Sign up for One Line Loop and you'll receive your first prompt tonight. Click the button in the email to write one line and start your one-line journaling habit. It's that simple — no setup required.
What time do I receive my daily log prompt?
You'll receive your daily log prompt at ~8pm in your local timezone. This timing helps you reflect on your day naturally without interrupting your routine.
Can I write my entry from my phone?
Yes! One Line Loop works on any device. Click the button in the email from your phone, tablet, or computer. Your daily log entries sync automatically across all devices.
What is the best journaling app for people who quit?
If you have quit journaling before, look for email-first delivery, a hard constraint (one line), and no blank-page guilt. One Line Loop sends one evening prompt, you write one encrypted line, and your streak updates automatically—built for people who never stick with journals.
Can I journal by replying to email only?
Yes. Reply to the evening prompt with your one line (≤120 characters) from the email on your account. You can also tap through to the web app. Replies are encrypted like app entries when encryption is enabled.
Is One Line Loop good for journaling after burnout?
Many users rebuild reflection after burnout with one short line and an external email cue—no long prompts or guilt when you skip. Start with a 7-day trial and write only when you have energy. See our journaling after burnout guide.
Does One Line Loop work if I have ADHD or a busy schedule?
The email cue and 120-character limit reduce executive-function load. You do not need to remember to open an app—the prompt arrives around 8pm local time in your inbox.
