Remember what you learn — without the endless re-reading and cramming

Multiple proven patterns — pick what fits you

• Build-as-you-go: Draw, place Lilypads, create labeled Frogs immediately, draw Pond, schedule first review.
• Clean-up then connect: Produce a “messy” map during focused study, review it a few times to consolidate, then add Frogs/Lilypads for connections once the structure is clearer.
• Cycle-powered review: Organize Lilypads or Frogs into folders (or use Pond ordering) and use the forward/back arrows in the menu to cycle through them in sequence — perfect for “predict what this connects to” active recall.
• Pond-focused deep work: Keep most work inside one or two Ponds. Use Pond View to dim everything else, warp from notifications or the Pond menu, and stay in flow.
• Folder-organized navigation: Drag Lilypads between folders, reorder inside folders, and cycle within a folder only when you want structured sequential review.

The in-app Help menus contain detailed “Pro Tips for Mind Mapping & Learning” for each mode — highly recommended reading once you start using the app.

How “Set next review” actually works

When you tap the clock icon in the Pond Editor (or “Set next review”), you see a hypothetical smart suggestion calculated from your previous review gaps, preferred time window (Morning / Afternoon / Evening / Any), and a sensible growth factor (~1.7× on longer intervals, faster growth on very short same-day intervals).

You can accept the suggestion as-is or easily tweak the hours and minutes. Then you confirm. That’s it.

No automatic scheduling after you mark a review complete. This is intentional:

• You might want the next interval shorter or longer than the suggestion.
• You might have forgotten to review for a few hours or days and want to adjust.
• You might decide you no longer need to review that Pond.
• You stay in complete control — the app never forces a schedule on you.

The smart logic is transparent and per-Pond: it remembers your preferred window and max auto-gap settings, shows you the previous interval and what the new gap will be, and lets you override anything. You can also manually set any future date/time.

Notifications respect your exact chosen time (down to the minute) and take you straight into the correct .HopMap file and the right Pond.

Lilypads, Frogs, Folders & Cycling

Lilypads are your named bookmarks. Tap any Lilypad in the menu (or from a notification) and the canvas warps to it and highlights it for 10 seconds. Perfect for jumping to key concepts during review.

Frogs are labeled connection hubs. You can link multiple Lilypads to a Frog and see the relationship clearly (e.g. “requires”, “improves”, “causes”). Tap a Frog to warp to it. Frogs and Lilypads both show which Pond(s) they belong to in their displayed name.

Folders let you organize Lilypads (and Frogs have similar organization). Drag to reorder, drag Lilypads between folders, and use the cycling arrows in the Lilypad/Frog menu to go forward or backward through the current folder or across all folders (depending on your “Cycle within folder” setting).

This gives you multiple powerful review modalities: sequential cycling for structured retrieval practice, random access via search or direct tap, and notification-driven focused review inside a Pond.

Group, focus, and review without distraction

Draw or spray a Pond around any group of strokes, Lilypads, Frogs, and Media. Everything inside belongs to that Pond. You can move the Pond, reorder content inside it, set a precise “notification entry point” (anchor), and enable phone notifications with smart timing.

Pond View dims everything outside the selected Pond (including drawings, Lilypads, Frogs, and Media) so you can concentrate on exactly the material you’re reviewing right now.

Notifications + Pond View + instant warp = the fastest path from “I should review this” to actually doing high-quality, focused recall.

The little reviews replace the big cramming sessions

Yes, the short reviews take a few minutes each — but they replace hours of painful re-reading and cramming later. Here’s what the research on spaced repetition + active recall shows when you replace “re-read everything” with visual maps + smart, focused reviews:

Bottom line from the studies: Once the spaced-review habit is in place (usually after the first 3–4 weeks), most learners cut total study time by 30–50 % while remembering 2–4× more long-term. The smart suggestions + Pond View + one-tap warping make those short reviews actually happen instead of being postponed forever.

The science foundation is solid: drawing for dual-coding and active encoding, explicit labeled connections (Frogs) for building rich associative networks, retrieval practice via cycling / predicting before warping, and expanding intervals tailored to your real history.

Test Canvas – experiment with zero risk

Open the in-app Help menu → tap any mode’s “Open Full Test Canvas” button. You can try drawing, erasing, Lilypads, Frogs, Media, Ponds, cycling, reordering — everything works live and isolated. Notifications and some Pro-only menu actions are intentionally disabled in the test canvas (they require a saved file and would take you out of the test environment anyway).

Once you’re ready, create a real .HopMap file, build your first Pond, and try the full smart review flow. The in-app Help menus for every mode contain extensive “Pro Tips for Mind Mapping & Learning” written specifically to help you get the most out of the system.

Pro is a one-time unlock (or subscription) that gives you the complete navigation + review toolkit. Free users still get a very capable infinite canvas with drawing, media, selection, and undo/redo.

HopMap is designed to operate entirely on your device without collecting, storing, or transmitting any personal or user data to us or third parties. All processing—such as creating, editing, saving, and reviewing HopMap files (e.g., .HopMap or .json formats)—happens locally in your device's memory or storage.

• No Personal Data Collected: We do not collect, access, or store any personally identifiable information (PII), such as your name, email address, device ID, location, or usage analytics.
• No App Activity Data: We do not track your interactions within the App, such as features used, session duration, or content created.
• No Device or Performance Data: No crash reports, diagnostics, or telemetry are sent off-device.
• Local Files Only: HopMap files you create are saved to your device's local storage. Any sharing (e.g., via copy/paste, export, or OS share sheet to services like Google Drive) is initiated and controlled by you, and we do not facilitate or monitor these actions.
• Media Content (Images & GIFs): Using Media mode, you can add images and animated GIFs directly to your canvas. These media files are stored entirely locally as part of your .HopMap files. The app never uploads, scans, moderates, or transmits any media content off your device.
• Encryption Feature: Encrypted saving uses a user-provided password to secure file contents on-device via AES-CBC encryption with PBKDF2 key derivation. The password is used only during save/load and is not stored, transmitted, or accessible to us. We do not guarantee recoverability (lost passwords mean irrecoverable files) or security against advanced attacks—this is a convenience feature, not a professional encryption tool.

In summary: No data of any kind is sent to the developer or any third party except for standard Google Play Billing requests (handled securely and privately by Google) when checking subscription status or processing a purchase.

Billing Data: Google may collect standard billing info (e.g., payment method, transaction history) per their Privacy Policy. We access none of it—your subscription is processed end-to-end by Google.

To provide core functionality, HopMap requests the following Android permissions. These are used solely for on-device operations and do not involve data transmission:

We request these permissions at runtime where required and explain their use. You can revoke them via your device settings at any time, though this may limit App functionality.

HopMap integrates minimal third-party services, all focused on local or anonymized operations:

• Google Play Billing: For freemium features (e.g., subscriptions to unlock advanced modes). All payment processing, including purchase data and billing info, is handled entirely by Google. We receive no payment details, user identifiers, or transaction history—only an anonymized entitlement token confirming whether premium features should be unlocked. To support seamless offline use, HopMap caches this token locally after initial verification, granting access until the end of your paid billing period. For accuracy (e.g., cancellations or refunds), the app performs light verification checks on launch or resume when online—connect periodically to ensure continued access. See Google's Privacy Policy for details.
• Flutter Plugins: We use open-source libraries (e.g., file_picker, share_plus, flutter_local_notifications) for local file handling and notifications. These do not collect or share data off-device. Full list available in our pubspec.yaml (if hosted).

No advertising SDKs, analytics tools (e.g., Firebase Analytics), or trackers are included.

Since we collect no data:

• Use: All "data" (e.g., your canvas content) is processed ephemerally on-device for App features only, including local encryption/decryption during save/load.

Offline Subscription Access: Premium features remain active offline by trusting the cached paid period end-date. On cancel or payment failure, access continues until that date (your full paid time—no extras added). Refunds (Google's ~48-hour window) revoke immediately upon detection. We recommend connecting online occasionally (e.g., weekly) for verification—it's quick and keeps everything current.

• Sharing: We do not share, sell, or disclose any information about you. User-initiated shares (e.g., exporting files) are your responsibility and not mediated by us.

In the event of a device backup (e.g., via Google Drive), that's controlled by your OS/account settings—not the App.

HopMap now supports Media mode, which lets you add images and animated GIFs to your canvas. These become part of your local .HopMap files.

• All content you create—including any media—is stored only on your device and remains under your complete control.
• We do not review, moderate, scan, or have any visibility into the specific images, GIFs, or other content users add.
• Important: When you share a .HopMap file in any way, the recipient receives everything in that file, including any images or GIFs you added. Conversely, files you receive from others may contain media that is inappropriate, explicit, offensive, or unsuitable for certain audiences (including children).
• The developer cannot guarantee the suitability or appropriateness of any content in user-shared files. Please exercise caution and discretion when opening .HopMap files received from others.

This is a fully local, user-controlled app. You are responsible for the content you create and share.

HopMap is designed for users of all ages, including children aged 6 and above.

We do not collect, use, store, or share any personal information from any user — including children. No accounts, no analytics, no identifiers, no crash logs, nothing leaves the device except when the user explicitly shares a file themselves.

Because no personal information is ever collected or transmitted, HopMap fully complies with the Children’s Online Privacy Protection Act (COPPA), GDPR-K (EU/UK), and all similar children’s privacy laws worldwide. Parental consent is not required.

HopMap has been designed from the ground up to fully comply with Google Play Families Program policies and is intended to participate in the program.

In the Google Play Data safety section the app is declared as:

• No data collected
• No data shared

This declaration is accurate and complete.

All local operations use standard Android security (e.g., scoped storage for files). Encryption is implemented on-device but is not audited or warrantied for compliance (e.g., GDPR/HIPAA). We do not store data, so there's no central breach risk. Keep your device secure and use strong locks for sensitive HopMap files. Remember: Lost passwords cannot be recovered by us.

Depending on your location (e.g., GDPR in EU, CCPA in California), you may have rights to access, correct, delete, or object to data processing. Since we collect none, these are N/A—but contact us for clarification. For Google-handled billing data, exercise rights via your Google Account.

We may update this policy to reflect App changes. Significant updates will be notified in-app or via Play Store. Continued use after changes implies acceptance. Check back periodically.

For questions, concerns, or to exercise rights: Email hopmapdev@proton.me. We're a solo dev project, so responses may take a few days.

Thank you for using HopMap—we're building it to empower your ideas, not track them!
