Penlock

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.

PRIVACY Penlock does not collect any personal data. Your journal entries, photos, and preferences never leave your device. The only third-party service is RevenueCat for purchase validation — it never receives any of your journal content. Full privacy policy at tonybach.io/Penlock/privacy.
