A detailed, plain-language companion to how Lentri behaves on your device. Lentri is a local puzzle journal: box photos, progress, timers, finish photos, ratings, achievements, and simple stats.
You stay local. There is no Lentri account, password, or cloud profile inside the app experience described here.We describe behavior, not bureaucracy. This page is written so you know what to expect while you collect and complete puzzles.Questions? Write to Lentri9k2xw@outlook.com
What Lentri is
Lentri helps you turn real-world jigsaw puzzles into a tidy, visual archive on your phone. You photograph puzzle boxes to create entries, attach details such as title, brand, and piece count, and watch each puzzle move through simple states: not started, in progress, and completed. The interface is built around warm wood tones, amber highlights, and orange accents so the app feels like a small studio shelf rather than a spreadsheet.
Because Lentri does not require an account, your relationship with the app is immediate: install, open, and start adding puzzles. Nothing in this handbook implies a mandatory online identity or a central Lentri login gate.
Your creative space
You are encouraged to treat Lentri as a personal craft log. Capture honest photos of boxes and finished tables, adjust progress when life interrupts a session, and use the timer when you want a faithful record of how long a build took. Ratings after completion are yours to interpret: they are a memory aid for how tough or satisfying a puzzle felt, not a public scoreboard.
The achievement wall and analytics views exist to reward continuity. They summarize what you have already done so returning to the hobby feels grounded in evidence, not guesswork.
Acceptable use in practice
Lentri is meant for personal, peaceful documentation of puzzles you own or work on with permission. Do not use the app as a tool to harass others, to store imagery you do not have rights to use, or to misrepresent commercial inventory. If you photograph people, obtain their comfort and consent first; Lentri is not optimized as a portrait studio, but courtesy still applies.
Keep your device secure. Because data lives on the handset, a lost or unlocked phone exposes whatever you stored in Lentri the same way it would expose your photo library. Use the screen lock and system backup habits you already trust.
Optional purchases
Some flows may offer optional in-app purchases related to expanding how many puzzles you can keep or how you interact with certain limits. Purchases are handled through the platform store you installed from. Lentri does not operate a parallel web checkout inside this handbook narrative.
If a purchase fails, retry after checking store connectivity. If something looks wrong after a successful charge, contact the email on this page with a short description of what you tapped and what you expected to happen.
Changes over time
Lentri may gain new screens, gentler animations, or clearer labels as the product matures. When meaningful behavior shifts (for example, how photos are stored or what optional purchases include), this handbook should be refreshed. The version you are reading is bundled as a static HTML snapshot for easy reading offline or in preview tools.
Field notes
Day zero
Install Lentri, grant camera or library access only when a screen asks for it, and create your first box entry.
Mid-build
Use the ring progress control and timer to match how you actually pace a table session.
Finish line
Photograph the completed puzzle, add ratings, and let the achievement wall collect the win.
Later
Skim analytics when you want a bird's-eye view of totals across everything you logged.
Respectful tone
We want Lentri to feel calm. If any copy in the app ever feels confusing, tell us. If a button does not respond as you expect, describe the screen and we will chase it. Feedback sent to Lentri9k2xw@outlook.com is read as product conversation, not as paperwork.
Prefer clear subject lines like "Timer pause" or "Photo save loop".
Mention your device type and system version when something breaks.
Never send passwords; Lentri does not issue them.
Ownership of your archive
The photographs and notes you enter belong to your creative practice. Lentri organizes them on your behalf inside the sandbox the operating system gives the app. You may duplicate, export, or delete entries using controls the app exposes; there is no parallel Lentri cloud folder described in this handbook that claims co-ownership of your table photos.
If you collaborate on a giant puzzle with friends, etiquette still matters: only photograph people and spaces where everyone agrees to be documented.
Availability and care
Mobile products evolve with operating system updates. Lentri aims to remain compatible with current phones and tablets, yet hardware generations move quickly. If a screen misdraws after a major OS upgrade, send a screenshot and we will queue a visual fix.
Offline-first behavior means most journaling continues without constant network access. Store-dependent features (such as refreshing optional purchase catalogs) naturally wait until connectivity returns.
Leaving Lentri
You may stop using Lentri at any time. Removing the app through your home screen follows the same storage cleanup rules as other applications on your device. If you intend to wipe only Lentri while keeping other apps, use the system storage panel and confirm the data footprint you delete.
Returning later reinstalls a fresh shell; unless you restored from backup, earlier entries would not reappear automatically.
Community spirit
Lentri celebrates slow hobbies. Share screenshots of your achievement wall with friends if you like, but remember that exported images may include titles or piece counts you typed yourself. Double-check before posting anything publicly.
We enjoy hearing which parts of the workflow feel magical and which feel fiddly. That qualitative signal steers the next round of polish.
