Penlock

Write freely. Stay private.

Free · In‑App Purchases · Designed for iPad

Pay once. Journal forever. Your words stay on your device — no cloud, no servers, no subscriptions. The private journal that truly belongs to you. Penlock is a beautiful journaling app built on one principle: your words never leave your device. No cloud sync. No accounts. No servers. No subscriptions. Everything you write is stored locally on your iPhone — private by design, not as an afterthought. WRITE FREELY Create journal entries with rich text, attach photos, set your mood, and organize with custom colored tags. Whether it's a quick daily reflection or a detailed travel log, Penlock gives you everything you need — and nothing you don't. STAY PRIVATE Your journal is protected by Face ID or Touch ID. All data lives in Apple's secure local storage — never uploaded, never shared, never seen by anyone but you. Zero analytics, zero telemetry, zero exceptions. BUILD A HABIT Track your writing streak and keep the momentum going. Use built-in writing starters — gratitude, daily reflection, goal setting, weekly review, travel log — or create your own custom prompts to jump-start your writing. DISCOVER YOUR PAST The Timeline view lets you navigate entries by date at a glance. Memories shows you what you wrote on this day in previous years. Full-text search puts every thought you've ever written at your fingertips. ONE PRICE. YOURS FOREVER. Penlock is a one-time purchase. $7.99 — no subscription, no recurring charges, all future updates included. Try it free with up to 10 entries, then unlock everything for life. FEATURES · Unlimited journal entries (after one-time unlock) · Custom tags with 10 color options · Photo attachments — up to 10 per entry · Mood tracking with 12 emoji moods · Writing starters and custom templates · Writing streak tracker · On This Day memories · Timeline calendar view · Full-text search · Markdown export · Face ID / Touch ID protection · Daily writing reminders · No cloud, no accounts, no tracking · All future updates included PRIVACY Penlock does not collect any personal data.
